What person made The Homework Machine?

It was a comedic sort of science-fiction story that starred the character Danny Dunn. Danny Dunn was a kind of bargain basement Tom Swift. ( or to make the comparison truer, the analogy of the super-agile but non-flying Spider Man to the fully Super-Powered Superman might be made. Up to a point Spider-Man was a spoof on Superman,and like him, in his cover job, works for a newspaper. ( the Daily Bugle) Peter Parker was a Photographer, and used a Yashica 35 Camera- a type rarely used by Pressmen of the time ( 60"s) most by then used SLR" the Yashica he carried was a rangefinder model ( not the best choice for press Photography). so it goes.
