In 1951, Stanley Gill from the Mathematical Laboratory at the University of Cambridge published a paper called "The Diagnosis of Programmes on the EDSAC" in the Proceedings of the Royal Society of London.  In it, he describes how he created a single-stepping debugger for the EDSAC computer.  As an aside, the EDSAC was the first programmable general-purpose computer in the world, and the team around it built early versions of many of today's standard software tools such as the first bootloader and the first symbolic assembler, which was very visionary and an amazing feat of programming.
