Even Geniuses Pass Away
Today, I got the sad news that a dear friend and an early contributor to PatternBuilders passed away.
Andrew (Andrei) Leman was a gruff, kind and generous man who will be deeply missed. Andrei was also a very talented mathematician and software engineer who created some of the fundamental theories around the mathematics of graphs. His papers on that subject are still heavily cited.
More importantly Andrei was a loving husband to his wife Elena and a great friend and mentor to many, many folks.
He will be missed but his work and the respect and affection he engendered will endure.
пухом my friend.
