Role Summary

John Morley Scholes (1948–2019) was the lead developer of Dyalog APL in 1981, and a prominent APL designer, teacher, and promoter throughout the rest of his life. He designed and implemented dfns, which have been adopted in numerous recent APL dialects, and maintained the dfns workspace demonstrating their use. He is also known for presentations and papers, in many cases of a whimsical or humorous nature, relating to APL. His 2009 video on implementing Conway’s Game of Life has been widely viewed and introduced many APLers to the language.
