I feel similar for Computer Science as a whole field. It's weird to think that many of its founding fathers were still during a significant portion of my life.
Claude Shannon 2001
Edsger Dijkstra 2012
John McCarthy 2011
Niklaus Wirth 2024
Konrad Zuse 1995
Alonzo Church 1995
Jim Gray 2007/2012
Grace Hopper 1992
Even Alan Turing could still have been alive during my lifetime hadn't he been murdered.
Friedrich L. Baur, who died in 2015, still had an office at my university when I studied there and I often passed by, saw his name plate, and wondered if this was all real.
