| Abstract: | Summaries. The first experiments in leaf-casting as a mechanical method of infilling missing areas in damaged papers were carried out by Yulia Petrovna Nyuksha in the Saltykov-Schedrin Library in Leningrad in the late 1950s. Inspired by her work from 1961 on the author constructed a series of leaf-casting machines and installed a number of systems, initially in Sofia, Bulgaria and then, after 1969, in Israel. The improved models produced there have been acquired by a number of institutions in Europe and the Americas. Historical notes are here given of these developments and the influences of this work on the manufacture of leaf-casting equipment and its operation by others. |
