Barr Foundation was established in 1997 by Amos B. Hostetter, Jr., a cable television entrepreneur, and his wife, Barbara W. Hostetter, using proceeds from the sale of Continental Cablevision. Initially operating as a small family-led grantmaking organization, it expanded over time into a larger institutional foundation. Barbara W. Hostetter served for many years as board chair, and in 2025 the foundation appointed its first non-family chair. Jim Canales led the foundation as president for 11 years before Ali Noorani was appointed to succeed him in late 2025.
