Hank Ketcham and his son Dennis

 
      
Henry (Hank) King Ketcham  (March 14, 1920 – June 1, 2001)

Hank Ketcham created the Dennis the Menace comic strip, which he both
wrote and drew from 1951 to 1994, when he retired from working with the
daily cartoon and took up painting full time in his studio. Ketcham, who
was born in Seattle, Washington, received the Reuben Award for the
strip, which continues in the hands of capable artists today.
