Leo Jolley

Leo Jolley (19 Aug 1920, Preston – 25 Dec 1976, Great Missenden) was an English information scientist who chaired the Co‐ordinate Indexing Group of the Association of Specialist Libraries and Information Bureaux in the 1960s.[1] In 1977 Jolley was described by Keith Albarn and Jennifer Miall Smith as being one of the foremost thinkers in the area of data handling shortly after his death. They highlighted this through his conception of the holotheme as a demonstrable form of an inherent structure present in all knowledge.[2]: 18

Jolley was born John Lionel Jolley on 19 Aug 1920 in Grove House Nursing Home, Preston, Lancashire. His father was John Ernest Jolley and his mother Ethel Birch. He married Jessie Marian Holman. Their only child, a daughter, died in childhood.[3]
