Ron Graham (1935/10/31 -- 2020/07/06) was a mathematician that the
American Mathematical Society described as "one of the principal
architects of the rapid development worldwide of discrete mathematics
in recent years".  Most recently he was at the University of California,
San Diego, having moved on from a quite senior position at the Bell Labs
or AT&T research centre based at Murray Hill.  Just how senior he was
I've never been able to work out, as he was a modest and unassuming man.

of

]]]
Wikipedia lists him as having done important work in scheduling theory,
computational geometry, Ramsey theory, and quasi-randomness.  But this
doesn't really capture the man.

Ron was also a 7-ball juggler, an international standard gymnast and
trampoliner, was President of the International Jugglers Association,
all in addition to being a well-known and widely respected research
mathematician.  He was even featured in Ripley's Believe It or Not!

Ron regularly worked in close collaboration with PaulErdos, even to
the point of having a room in his house for Paul's use whenever he
turned up.

He was a genuinely lovely man, and even though I saw him rarely, he
was always warm and welcoming.

I will miss him.
