R. Crosby Kemper Jr., chairman emeritus of UMB Financial Corp., died Thursday in Kansas City, Mo., the company reported Friday. He was 86.

Kemper and his wife, Mary "Bebe" Stripp Kemper, owned homes in the Colorado Springs area in the late 1980s and early 1990s, and his family's Kemper Foundation is a major donor to the Cheyenne Mountain Zoo.

UMB is the largest bank in the Colorado Springs area with nearly $300 million in deposits in four branches. The Kansas City-based company acquired local banks in 1987, 1991 and 2008 and now operates banks in Colorado and six other states with combined assets of nearly $15 billion.

Kemper was born Feb. 22, 1927, and began his banking career at age 22 at his father's City National Bank as a night transit clerk assigned to meet trains and sort checks. He later became senior chairman and retired from the company in 2004.

He is survived by four daughters, three sons, 22 grandchildren and two great-grandchildren.
