Andrew (“Cap”) Tilles was born in St. Louis on November 27, 1847. The Tilles Foundation was originally called the Rosalie Tilles Non-sectarian Charity Fund, and was started as a Christmas gift to the underserved people of St. Louis from Cap Tilles as a tribute to his mother—Rosalie Peck Tilles—in 1926. Today, the Tilles Foundation makes approximately $700,000 in grants per year, and is managed by a Board of Trustees which meets at least 4 times a year.
