Sig, legendary investor and pioneer in growth equity investing, died Jan. 2, 2023, in New York City. With six others in 1969 he co-founded Jennison Associates, a manager of U.S. large cap growth stocks. He was also a generous donor to Annual Giving. 

Sig was born July 2, 1933, and at Trinity School was active in football, basketball, track, and student government.

At Princeton, he majored in economics and joined Cannon Club. He was involved in freshman football and track, as well as IAA football, basketball, and track. His senior-year roommates were John Sibley and Henry Kaplan. After graduation he served as an officer in the Navy.

Sig had unbridled optimism and loved traveling, photography, and the ocean. He cherished his family and encouraged them to pursue activities that brought them joy. He loved sports and watching his family compete. To his grandkids he was “Papou,” larger than life and perfectly imperfect. Upon meeting his first great-grandchild, he gave him his first Yankees cap. “I just want to make sure he’s raised right,” he said with a smile. “Go Yankees!” 

Sig was predeceased by his wife of 65 years, Diane. He is survived by children Anthony, Harry, Christine, and Daphne Sampson; 11 grandchildren; a great-grandson; brother Hercules; and sister Mary.
