I found another "Speedee" in Banning, 85 miles east of Los Angeles. Speedee was McDonald's icon from 1948 to 1960. Bozo The Clown, played by Willard Scott, replaced Speedee for three years until the first Ronald McDonald took over in 1966. The "Ronald" that we know today and are most familiar with made his debut in 1971 and has kept his job (and makeup) since.
For the record, I am not a fan of clowns; they freak me out. I'll stick with Speedee.
