|"The Curtas were marvels
of mechanical miniaturization which were introduced by Contina Ltd. in 1948. They were
designed by Curt Herzstark while he was a prisoner in a concentration camp. Herzstark
worked out the basic design in his head and polished it on paper when he was released in
1945. Herzstack's design was based on the stepped drum mechanism but with a brilliant
adaptation that allowed a remarkably simple and compact design. "
