Alumnus Byron Chrisman and his wife, Carlene, have pledged $10 million to the University of Colorado Law School as part of their estate. When realized upon their deaths, the donation will be the largest ever made to the Boulder law school.

Byron Chrisman graduated from Colorado Law in 1966 and went on to co-found what is now Boulder’s largest law firm: Chrisman Bynum & Johnson. He turned to commercial real estate development later in his career, and the companies he formed hold more than 700,000 square feet of commercial space. Chrisman retired from law practice in 1997.
