Howard Katseff See 3BSD: usr/doc/sdb/sdbrp.n and https://www.usenix.org/legacy/publications/library/proceedings/cinci93/full_papers/katseff.txt I had also done some interview with him. My Book (wip) says: Katseff, who had already graduated from Berkeley in August 1978, was working at Bell Labs in Holmdel in the group developing 32/V. He started working on sdb, a symbolic debugger for C language programs. It was used for debugging core images from aborted programs. It could report which original source code line caused the error, allowed access to variables, define breakpoints, calling procedures, and could single step on a line by line basis. (Haley and Joy had provided constructive criticism during the sdb development.) % cite: archives/1970s/3bsd/usr/doc/sdb/sdbrp.n % NOTE: Katseff didn't remember if that is for doc or code This debugger was transferred to Berkeley along with the rest of the 32/V operating system.\cite{katseff1}
