Early Life and Education

Timothy Springer was born in Fort Benning, Georgia, in 1948. His father was a physician.

During the Vietnam War, Springer volunteered as a VISTA community development volunteer on the Yomba Shoshone Reservation in Nevada.

Springer founded LeukoSite in 1993, which went public in 1997 and was acquired by Millennium Pharmaceuticals in 1999. Springer's early investments in companies like Moderna, where he invested $5 million in 2010, proved highly lucrative, contributing significantly to his wealth.
