Calvin Simmons Middle School is named for him, as is the theater at the Kaiser Convention Center. He is one of the people featured on the mural "Grand Performance" on Grand Avenue, under the I-580 overpass near MacArthur. He's on the left side, an area of the mural that's most exposed to the weather.
