John Glashan (born John McGlashan, 24 December 1927 to 15 June 1999) was a Scottish cartoonist, illustrator and playwright. He was the creator of the "Genius" cartoons. Glashan's cartoons typically included small pen-and-ink figures drawn over a fabulous backdrop often featuring fantastic Gothic or imaginary architecture, surreal landscapes or gloriously impractical ingenious-looking machines.
