The close of my studies with a degree of a Dr. Ing. in 1929 coincided with the great economic crisis, and I was not able to find an academic position. I was therefore very grateful for a position in the newly created laboratory of G.J. Driza in Prague where rare chemicals were produced on small scale.

To grasp the essence of chirality, it is instructive to withdraw for a moment from the familiar three-dimensional world into a two-dimensional one, into a plane, and enquire what chirality means there.

The period 1924 to 1929 was spent studying chemistry at the Czech Institute of Technology in Prague, Czechoslovakia. The supervisor of my thesis was Professor Emil Votocek, one of the prominent founders of chemical research in Czechoslovakia.
