The son of the chemical engineer Julius Lewkowitsch, Farradane graduated in chemistry in 1929 at what is now Imperial College and started work in industry as a chemist and documentalist. After working in research at the Ministry of Supply and the Admiralty during World War II, he first made an impact with a paper on the scientific approach to documentation at a Royal Society Scientific Information Conference in 1948.
He was instrumental in establishing the Institute of Information Scientists in 1958 and the first academic courses in information science in 1963 at what eventually became City University, London and where he became Director of the Centre for Information Science in 1966. Of Central European origin, his commitment to science was reflected in the name he created for himself - a combination of Faraday and Haldane, two scientists he particularly admired. On the research side his main contributions lay in relational analysis, a precursor to work in the area of artificial intelligence, and the concept of information.

- Abstract: A probabilistic model of the retrieval process is presented. From it, the standard errors of system recall and precision estimators, based on a sample of queries, are derived. The resulting negative binomial model is fitted to empirical data from several retrieval tests.
