<abstract>Michael Dallwitz joined the CSIRO Division of Entomology in 1970 where he supervised the Divisional computing unit from 1974 to 1992, and consulted with staff in the development of general-purpose software. His major achievement was the DELTA software, a flexible data format, capable of representing most types of information used by taxonomists for description, identification, and classification of living organisms. DELTA was used worldwide from 1985 in taxonomic research and for teaching. Dallwitz presented numerous workshops on the use of DELTA. He left CSIRO in 2000 when DELTA was closed.</abstract>
<p>In 1996 Dallwitz was awarded the CSIRO Medal for Research Achievement for his development of the DELTA taxonomic computer programs.</p>
