On June 30, 2019, Mitchell Feigenbaum, one of the outstanding pioneers of chaos theory, died at the age of 74. In 1975 he discovered with an HP-65 calculator that the ratio of successive distances between bifurcation events tends to a constant value, which was later termed Feigenbaum constant. This was one of the founding events of chaos theory and nonlinear dynamics.

Dam; I was hoping to find him for a conference presentation.
I too was fidgeting with iterative calculations on my 65 back in 1974.
He took things a bit farther than I did!

This is indeed sad :'( . He died so young -- my grandfather recently died and he was almost 100.
I was also sad when Michael Golomb died at 98. He was the person who came up with all Purdue's higher math Problems of the Week. Apparently though, there is still a backlog of problems that have yet to be published as Michael Golomb was so prolific.
R.I.P. to both of them.

Condolences and comfort to the Feigenbaum family.
