Here’s a guy with one of the best aptonyms I know of: Dill Pickle (1924-2016), pickle salesman.
Here’s an article about him:

I haven’t been able to figure out what the middle initial “L” stands for, but I can tell you that “Dill” was a hand-me-down from Dill’s father, Curtis Dill Pickle (1899-1970).
Update, Jun. 2022: I was recently contacted by Dill Pickle’s daughter, who kindly gave me some extra information, including Dill’s middle name: Lamar. Thank you!
