# Hans Wellisch

Hans Hanan Wellisch (April 25, 1920 – February 6, 2004) was a librarian, LIS educator, and indexer known for his work with the International Federation for Documentation (later International Federation for Information and Documentation), contributing to the Universal Decimal Classification. He headed the committee which translated the abridgement of the UDC into Hebrew and was the compiler of the index to the system.
Wellisch had a younger brother, Ellie, and was the son of a newspaper advertising father and secretary turned housewife mother.He was set to graduate after eight years of European high school, which entitled him to enrollment in a university. Even though Wellisch’s academic career was straightforward at this point in his life, he was destined to take a different path. His road to becoming a writer and teacher of classification and cataloging was quite different than many of his other peers within the same field.
After graduating from high school and just a few weeks before receiving his matriculation certification, Wellisch was arrested in November 1938 and sent to Dachau concentration camp. When arrested he already had a visa to Sweden, so he was sent there after two and a half months. There he briefly worked in the special library of the Swedish Cooperative Federation which gave him some training in librarianship. He emigrated to Israel in 1949 where he was the librarian of the Signal Corps of the Israel Defense Forces. He received a grant from the United Nations to study at the University of Maryland in 1967. The university invited him to join the School of Library Science as a visiting lecturer two years later. He worked there for the rest of his professional career, and earned a Masters in Library Science in 1972 and a Ph.D. in 1975. He retired from UMD in 1989 as a full professor.
He was the first recipient of the American Society for Indexing Award for the index to his book, The Conversion of Scripts: Its Nature, History and Utilization. He also won the Hines Award for "continuous dedicated and exceptional service" to the ASI where he was president from 1984 to 1985.
