December 31, 1940 - October 17, 2025
Alexander J. Thomson, a proud New Yorker, West Point graduate, and accomplished businessman, lived a life defined by integrity, leadership, generosity, and quiet strength.
Born and raised in Elmsford, New York, Alexander grew up in a close-knit family that valued hard work and community. He was the son of Eleanore and Alexander "Scotty" Thomson, and grew up alongside his beloved brothers, John and Frank, and sisters, Barbara and Ann. His father owned Brady's Diner, a beloved local establishment where all of the Thomson children worked and learned the importance of dedication, responsibility, and family. He attended Alexander Hamilton High School, where his drive and discipline began to shine through—qualities that would later define his life and career.
A graduate of the United States Military Academy at West Point, Alexander was commissioned as an officer in the U.S. Army and honorably served his country during the Vietnam War. During his service, he was awarded the Army Commendation Medal for Merit, among several other honors recognizing his outstanding leadership and dedication. Though a decorated veteran, Alexander carried his service with humility, rarely drawing attention to his accomplishments.
Following his military service, Alexander began a distinguished career in finance with Citibank. His work took him to Brazil, where he lived and worked before returning to New York City to continue his career within Citibank's asset management division.
In 1982, Alexander and two colleagues, Richard A. Horstmann and William C. Bryant, departed Citibank to establish their own asset management firm—Thomson, Horstmann & Bryant, Inc., headquartered in Saddle Brook, New Jersey. It was not a coin-flip that determined the sequence of the names identifying the firm; Alexander was a natural-born leader, a quality shaped by his days at West Point.
Under his guidance, the firm became one of the nation's most recognized small-company investment specialists. By the early 1990s, Thomson, Horstmann & Bryant managed over $2 billion in assets and gained a reputation for excellence and integrity in the investment community.
In 1998, the firm was acquired by United Asset Management Company, a NYSE-listed, Boston-based corporation. Alexander continued to lead and mentor the next generation of investment professionals before transitioning into a well-earned retirement in Palm Beach, Florida. Over the course of his career, he was widely respected as an exceptional investor, a thoughtful mentor, and a man whose word carried weight and trust.
Alexander was a generous man, known for his kindness, sharp wit, and unwavering loyalty to those he loved. He enjoyed golfing, traveling, and spending time with family, especially evenings at the grill cooking steaks, sharing laughter, and ending the night with a nice scotch on the rocks.
He is survived by his devoted wife of 27 years, Jeanine, his four beloved daughters—Sophia, Divina, Christine, and Jaqueline—his brother John, his sister Barbara, and his cherished grandchildren, Ellie and Mikey.
He is rejoicing in heaven with his loving parents, Eleanor and Alexander, his brother Frank, his sister Ann, his son-in-law and best friend Andrew Robins, and the many beloved family members and friends who went before him.
Alexander served his family, his country, and his clients with loyalty and grace. He will be remembered for his sharp intellect, strong moral compass, generosity of spirit, and the quiet but profound impact he had on all who knew him.
His legacy will live on through the countless lives he touched—through his devotion to family, his integrity in business, and the example he set of strength guided by humility. Those who knew him will carry forward his lessons of hard work, honor, and love. Though his presence will be deeply missed, his spirit remains ever present in the hearts of those who had the privilege to know and love him.
