My racket is mathematical typography. I worked for a professional society and publisher of mathematics for 56 years, before retiring in 2019. For most of that time I assisted mathematicians in solving problems preparing their computer files for publication. I've been a jigsaw puzzle addict since I was big enough to arrange the pieces instead of trying to eat them, and have a fine collection of the "traditional" variety. I love this site! And have introduced friends, with great pleasure for both them and me.
I joined Jigidi on 3 April 2011 and was last seen on 29 November 2021. I've solved 23443 puzzles (6 daily) and put together 2050169 pieces (526.6 daily)
