Bicentennial Medalists 2019

About the Award

Established in 1993 on the occasion of the college’s 200th anniversary, Bicentennial Medals honor members of the Williams community for distinguished achievement in any field of endeavor. The college awarded 23 Bicentennial Medals in 1993 and has added up to seven awardees in each year since.

The Bicentennial Medals recognize alumni for “significant achievement in any field of endeavor.” We hope that seniors will find the recipients’ career paths and their accomplishments inspiring as they begin to think of life after college.
