The Leo Block Alumni Center is named for former Clarion editor Leo Block, BA social sciences ’35. After serving in World War II, Block started a wine and liquor distribution business in San Antonio; the company became the largest distributor in south Texas. In 1987 Block gave the University $1 million to endow the Leo Block University Professorship. In 1992, the University honored Block with the Evans Award, and in 1996, DU dedicated its alumni center in his honor.
