As a budding ham and paleo-geek, I was naturally drawn to the idea of building an automatic Morse Code sender instead of, you know, actually learning to do it competently with a straight key! This was not my design, though it had a number of modifications; it ended up mounted on the side of my equipment rack in the basement lab and seeing occasional use on the 40- and 80-meter CW novice sub-bands back in the sixties. 

The designer of this was Morris Grossman, and it was published in Electronics Illustrated magazine. You can find the article (PDF, page 17) at the American Radio History site.
