I look for a lost paper of D.N. Lehmer on bimagic squares. He presented his paper in an AMS meeting, UCLA, in 1934. More details here: http://cboyer.club.fr/multimagie/English/Smallestbi.htm#DNLehmer Do you think that there is a small chance to find this paper through his daughter-in-law, Emma Lehmer (or family)? I hesitate to send her a letter on this subject.

Lehmer, and many other renowned number theorists - is in the Oxford 1969 photograph at my web site http://www.spd.dcu.ie/johnbcos/oxford.htm.
