ST. LOUIS (AP) — A couple who ran a machine shop and invested wisely has left a total of $25 million to two St. Louis hospitals.

The estate of Howard and Dorothea Hebebrand left the bequest, which will be divided evenly between St. Louis Children's Hospital Foundation and Shriners Hospital for Children-St. Louis. Hospital officials expressed their gratitude to the couple on Monday.

The St. Louis Post-Dispatch reports Howard Hebebrand died in 1997 and his wife died in 2012. The couple had no children.

Howard Hebebrand grew up in St. Louis and attended Washington University. He was president and owner of Design Manufacturing & Equipment Co. and also owned Bates Sales Co., a supplier of power transmission equipment. His wife was vice president.

The couple retired in the 1960s.
