John Jacob Astor IV was an American business magnate, real estate developer, investor, and writer. Born in 1864 into the prominent Astor and Livingston families, he built a multi-faceted career that spanned commerce, literature, and military service. Beyond his extensive real estate holdings and investment ventures, Astor was a writer and served as a lieutenant colonel in the United States Army during the Spanish–American War, reflecting his active participation in the civic and military affairs of his era. Astor is most widely remembered as the wealthiest passenger aboard the RMS Titanic during its ill-fated maiden voyage in April 1912. At the time of the disaster, he was considered among the richest people in the world, possessing an estimated net worth of roughly $87 million. His tragic death, alongside 1,495 other passengers and crew members when the ship sank in the North Atlantic, became one of the most prominent stories of the disaster, cementing his legacy in modern history.
