A posthumous Paul Erdős signature
Added 2024-10-12 09:40:15 +0000 UTCI was back in the Numberphile "archive" yesterday sorting through old brown papers... and I came across this one.
It is from a video with the late Ron Graham in which we discussed his close relationship with Paul Erdős.
Graham handled all paperwork and finances for the eccentric Erdős... and also signed his name quite often.
On this paper from 2014, Graham signed it as Erdős too.
Erdős had died in 1996. Graham died in 2020.
Comments
I work at UCSD and have met Ron Graham once years ago but never got to talk to him at length. His wife Fan Graham is still a Professor and though I have worked with her (on IT matters) I wonder if that still qualifies as a Erdős number?
