Frederick Wilfrid Lancaster
Frederick Wilfrid ("Wilf") Lancaster (September 4, 1933 - August 25, 2013) was a British-American information scientist. He immigrated to the USA in 1959 and worked as information specialist for the National Library of Medicine in Bethesda, Maryland from 1965–68. He was a professor at the University of Illinois, Urbana from 1972-92 and professor emeritus from 1992-2013. He continued as an honored scholar after retirement speaking on the evolution of librarianship in the 20th and 21st century. 
F. W. Lancaster was in particular known for his work on online retrieval including evaluation studies of the MEDLARS-system. He has, however, an unusual broad and comprehensive authorship in Library and Information Science (LIS). Over a period of four decades he continuously emerged as a visionary leader in the field of LIS. His research, writings, and teachings earned him the highest honors in the profession. Lancaster excelled at many fronts: as scholar, educator, mentor, and writer.
