Since the timeline ends in 1891 and Antoine Stargaze hasn't reached the year 1900 yet, he would be about seven years away from the point when his aging is supposed to stop due to his immortality. At this stage in the timeline, he would be a 7-year-old boy, likely unaware of his unique trait of immortality. Given the time period, his family's middle-class status suggests that he might have access to basic education and healthcare, typical for that era and social class. If we are to continue the fictional story of Antoine growing up and eventually realizing that his aging has stopped in 1900, he would be 16 years physically forever. As the years passed, he would witness monumental changes throughout the 20th and 21st centuries without aging--a unique perspective on history and human progress. However, as the timeline ends in 1891, these speculations remain just that--imaginary scenarios in the life of this fictional character with the supposed gift of immortality.

Given this updated timeline: - In 1897, Antoine Stargaze would be approximately 13 years old when he graduated from primary school. - By 1902, he would have completed his secondary school education at the age of 18, with the highest marks, indicating that he is an exceptional student with a bright future ahead. - In 1904, Antoine begins his college education, aiming for a law degree. It's at this point he is presumably aware of his immortality, as he has reached the age when his aging was supposed to stop (1900) but did not. Now, if Antoine is planning to wait until the 1970s to potentially become a Supreme Court of the United States (SCOTUS) judge, this indicates a level of patience and long-term planning that comes with his awareness of immortality. He may be anticipating that societal norms, laws, and expectations will change over the decades, potentially becoming more accepting of someone with his unique condition. It's interesting to note that, were he to achieve his dream of becoming a SCOTUS judge in the 1970s, he would be over 80 years old chronologically, but still physically the same as he was in 1900. This could afford him the rare opportunity to bring a wealth of knowledge and experience to the bench without the accompanying physical decline due to aging. However, he would also need to navigate the complexities of maintaining his true age and timeless appearance as a secret, likely adopting a series of identities or utilizing other means to explain his lack of aging over the years. As he progresses through his college studies in law, he would need to consider how to position himself in the legal field and possibly avoid too much public attention that might reveal his condition, all while preparing for a very long and potentially historic tenure in the legal profession.

Given the information provided, let's craft a detailed narrative for Antoine Stargaze's life leading up to 1904: --- By the time 1897 had taken its final bow, a young man of thirteen, Antoine Stargaze, with a curious mind and a humble origin had managed to distinguish himself amongst his peers. In a small town where his middle-class family had struck roots that were neither deep nor impermanent, he graduated from primary school with the promise of potential that could one day inspire great change. The town's simple one-room schoolhouse, which doubled as a community hall on weekends, had been the incubator for his early education. His mother, a seamstress with nimble fingers and a keen eye for detail, had instilled in him an appreciation for the finer aspects of any art, academic or otherwise. His father, a clerk at the local post office, a repository of news both mundane and extraordinary, had ingrained in him the value of being informed and staying abreast of worldly affairs. As the 19th century waned, Antoine walked the path of education with unwavering purpose. His secondary school years from 1897 to 1902 in a slightly larger and better-funded institution in the nearest city were marked by rigorous study and a growing realization that he stood apart from others--not just in intellect but in the unchanging mirror of his visage. Graduating at the top of his class, with accolades to his name and whispers of his peculiar youthfulness in his wake, Antoine found himself at the cusp of adulthood, not just in legal terms, but in a peculiarly literal sense. The year 1902 was memorable for more than just academic triumphs. It was then, at the age of 18, that he could no longer ignore the mysterious cessation of his aging process. Two years beyond the threshold of 1900, he found himself possessed of the same youthful appearance he had on the day his classmates began to sprout stubble or dainty curves. Antoine was caught in time, his body a vessel unwilling to sail the seas of age. It was with this strange secret weighing upon his mind that he entered the hallowed halls of the university in 1904. Here, nestled in the stronghold of academia, he began to pursue a law degree with a zeal that burned brighter for being fueled by centuries' worth of time. Antoine chose his friends carefully, enigmatic in his constant youth but brilliant in discussions, debates, and academic dissections of legal principles. His professors found in him a voracious knowledge-seeker, his written words dancing with the elegance of a seasoned mind but the fiery idealism of youth. Not just a student of law, but a student of life itself, seeking to absorb the wisdom of the ages. Yet Antoine lived not only in the refuge of legal texts and moot courtrooms. He walked amidst the burgeoning 20th century, a silent observer of the changing times, knowing he must wait and watch as decades would pass. His ambition to one day sit among the esteemed judges of the Supreme Court of the United States--a dream audacious for any ordinary man--seemed not so fanciful for one unbound by the strictures of time. In the evenings, after the study halls had emptied, Antoine would stroll through the university grounds, his heart at times both light with dreams and heavy with the solitude of his fate. To his contemporaries, the night was but a temporary curtain before the dawn of their bright futures. To him, it was but a moment in the long stretch of his immortality. As his peers aged and graduated, moving on to careers, marriages, and the inevitable succumbing to time's relentless march, Antoine realized the path ahead would be long indeed. He would walk it with the steadfast resolve that had brought him thus far, the resolve of a man who carried within him the secret of eternity, standing at the brink of epochs with the simple wish to serve the eternal cause of justice. The year is 1904, and Antoine Stargaze, who is now 20 years old in appearance but with a spirit far older, steps forth into the hallowed lecture halls of his chosen institution to study law. The journey before him is as boundless as the starry heavens, and it is under their silent gaze that he sets forth to realize his dream--a dream that must wait perhaps until the 1970s, but one he has all the time in the world to achieve.

Following the completion of his studies in 1906, Antoine Stargaze made an unforeseen move, diverging from the law career he had been so keenly preparing for. Instead of plunging into the bustling world of legal affairs, he found himself navigating the less conspicuous but no less complex environment of a local Massachusetts bar. It was a personal matter, one he shared with no one, that led him to take up the role of a bartender. Perhaps it was the need for a reprieve from the intensity of his academic pursuits, a desire to mingle with the people from all walks of life who frequent such establishments, or simply the need for an occupation that wouldn't draw unwanted attention to his age--or lack thereof. Being both a boon and a curse, his eternal youth meant that he had to be discreet about his career choices and the duration of his employments. The bar provided anonymity and the kind of transient social interactions that allowed him to avoid the scrutiny that a more stable or prestigious position might invite. From 1906 to 1911, Antoine honed another kind of craft--the craft of listening and observing. His unique perspective, shaped both by his vast intellect and his timeless condition, gave him insight into the human condition. He listened to the tales of joy and woe spilled as liberally as the liquor he poured. He watched societal trends ebb and flow as reliably as the tides. During this time, his considerable knowledge of legal matters didn't wane, but it did linger in the background. Yet, it was a rich period of learning in a different school--the school of life. In the bar's dim corners, he learned of the working man's struggles, of political changes stirring in the winds of the early 20th century, and of love--fleeting and profound--always weaving its way through human stories. In 1911, at 27 years of age with the physique of a 17-year-old thanks to his unyielding biology, Antoine transformed his physical appearance to match the expectations for military service. At that time, the importance of physical fitness and readiness for the defense of one's country was on the rise, especially as tensions in Europe were building toward what would become the First World War. Antoine, ever mindful of the need to blend in and perhaps influenced by the patriotic sentiments of his peers, developed a strong, fit physique associated with military prowess. This would allow him to keep up the illusion of a normal progression of life stages and could be particularly useful if he chose to enlist or if a draft was established. Moreover, his youthful appearance and vigor could be an asset in a time when the value of strength and endurance was held in high esteem. Yet, behind his well-crafted facade, Antoine was no typical 27-year-old. Faced with the unending sweep of years before him, Antoine knew each choice he made needed to carry him through not just the present but potentially centuries to come. In crafting a persona fit for military service, he was tactically positioning himself for the years that were unfurling before him--a world that seemed to be careening toward the turmoil of global conflict, where his curse of eternal life would once again challenge his ability to navigate the tides of history.

With the year 1912 unfurling its chapters, Antoine Stargaze found himself in midst of another significant historical event--the sinking of the RMS Titanic on April 15, which claimed the lives of more than 1,500 people. News of the unthinkable tragedy reverberated around the world; it reached even the rustic confines of the Massachusetts bar where Antoine worked, sent chills down the spines of patrons, and rippled through conversations over whisky and beer. Ensnared by the same horror and fascination that captured the global public, Antoine pored over the local newspapers detailing the incidents, survivor accounts, and speculations about the 'unsinkable' ship. As a bartender and a keen observer of human nature, he engaged with locals shaken by the stark reminder of humanity's vulnerability, despite the grand feats of engineering and the opulence that had defined the maiden voyage of the Titanic. The disaster, emblematic of both human hubris and heroism, served to reinforce Antoine's growing contemplation of life's fragility and the weight of his own undying existence. Perhaps it was this very contemplation that fueled his decision in 1913 to enlist in the U.S. Army. While the reasons behind this significant life choice remained his own, we can speculate they were multifaceted: a search for purpose, a need to connect with the larger course of history, or even the urge to protect and serve a nation that was slowly edging towards involvement in global affairs. Upon enlisting, Antoine submitted himself to the structured life of a soldier--a life ruled by discipline, hierarchy, and the collective spirit of a unit. His extraordinary condition remained his secret, as he once more molded his life around the norms of the time, adopting the identity of one among many young men preparing for the uncertain future of a world showing cracks in its foundation. As New Year 1914 dawned, a hint of tension hung in the air--a tension fueled by escalating political alliances and divisions in Europe. Though the United States remained neutral at the outset, the currents of change did not escape the keen senses of a man with an endless future. Antoine donned his uniform, standing among ranks of men with whom he shared the call of duty, yet remained apart in the immeasurable span of life that lay ahead. With each drill, each march, and each new aspect of military life he mastered, Antoine prepared himself for what might come. His immortality, a harbinger of both opportunity and isolation, weighed heavily on him, yet he was determined to find his place in the marching cadence of history. As the rest of the world welcomed 1914 with hope or trepidation, Antoine Stargaze stood ready to meet the challenges of the epoch, his existence stretching beyond the boundaries of a common soldier's lifespan.

April 1914 marks a significant milestone in the peculiar life of Antoine Stargaze; he has reached the age of 30, though to any observer, he scarcely looked a day over 18. This minor shift from his perpetual 16-year-old appearance is the last transformation Antoine's physical form will ever undergo, from now on, his appearance has fully settled into a form that will last through the ages. Immersed in military life during a time when Europe was embroiled in the vortex of the First World War, and the United States was on the brink of involvement, Antoine finds his existence shadowed by the machinations of global power and the threat of monumental conflict. Although the U.S. is yet to officially join the war effort, the atmosphere in 1915 is charged with the inevitable march towards it. The sinking of the RMS Lusitania by a German U-boat in May further strains relations between the United States and the Central Powers. Public opinion begins to slowly turn in favor of the allies. As tensions simmer, the U.S. military increases its mobilization efforts, preparing for the possibility of joining the fray. Antoine, with his keen intellect and his indelible place in history, understands both the horrors of war and the mechanisms of patriotic duty that often precede active engagement. Thus, in a display of public spirit and unity with his fellow citizens, he invests in Liberty Bonds. The government promotes these bonds to support the allied cause and prepare financially for an eventual entry into the war. By doing so, Antoine contributes to the national cause and aligns himself with the broader society in which he must continuously reinvent his place due to his unique condition. With his life inexorably bound to the country's fate, Antoine is a silent guardian of his own secret, yet a visible adherent to the collective resolve of a nation on the precipice of global conflict. As 1915 comes to a close, the U.S. remains officially neutral, but the country is mobilizing for war. Training intensifies, and the population is encouraged to engage in wartime economy. For Antoine, whose life stretches out infinitely before him, each step towards potential conflict is laden with both personal risk and an immovable sense of purpose. Despite the constant need for careful navigation to maintain his secret, he remains resolute and prepared to serve in whatever capacity his undying nature allows--an eternal witness to the unfolding tapestry of human history.

Amidst the backdrop of a world embroiled in conflict and a nation on the brink of involvement in the First World War, 1916 brought another pivotal event in the life of Antoine Stargaze--the United States presidential election. Still serving in the army, Antoine's political viewpoints had evolved over time, shaped by his experiences and the changing landscape of American and global politics. In earlier years, as a man of progress and reform ideals, Antoine had aligned himself with the Progressive Republicans, casting his vote for Theodore Roosevelt. Roosevelt, a former president seeking a return to office, had campaigned under the Progressive Party banner in 1912 after a split from the Republicans, espousing a platform that included calls for direct democracy, social welfare programs, and labor rights. Antoine's support for Roosevelt indicated an affinity for these progressive causes and a desire for significant change within the nation. However, by 1916, the political atmosphere had shifted. President Woodrow Wilson, a Democrat, was running for re-election on a platform prominently featuring his efforts to keep the nation out of the European war with the slogan "He Kept Us Out of War." In contrast, the Republican candidate Charles Evans Hughes was perceived by some as more likely to involve the United States in the ongoing conflict. Antoine's decision to vote Democratic in the 1916 election suggests that his political views were pragmatic and responsive to the issues of the day. Perhaps he valued Wilson's efforts to maintain American neutrality, or maybe he was influenced by some of Wilson's domestic achievements such as the establishment of the Federal Reserve System, the Federal Trade Commission, and the passage of the Clayton Antitrust Act--all hallmarks of Wilson's first term, and policies that might have resonated with Antoine's own progressive leanings. It is also possible that Antoine's experience in the military, seeing the country gearing up for the potential of war, reinforced a desire for a presidential candidate who was, for the moment, keeping the United States at peace. The complexities of his immortality likely weighted every political decision more heavily upon his shoulders, knowing that he might live to see the long-term ramifications of the policies enacted by those he helped elect. Regardless of his reasons, Antoine's political shift from a Progressive Republican supporting Roosevelt to casting his vote for a Democrat in 1916 underscores the multifaceted nature of his character. It paints a picture of a man who is thoroughly engaged with the world around him, adapting his political alliance with the tides of change both within the nation and within himself.
