For many years, most of the Taylor donations were through the Enterprise Rent-A-Car Foundation, managed by his daughter, Jo Ann Kindle. The company donated more than 1 percent of its annual profits to charity.

Mr. Taylor said he ultimately realized that the old saw, “I gave at the office,” wasn’t good enough. For one thing, he said, “I didn’t want people to think the Taylor family is making all that money and doesn’t do a damn thing for the city.”

He also said wanted clients and prospective employees to see St. Louis as big-league, with good sports teams, cultural centers and educational institutions.
