Elizabeth Y. Haworth has authored or co-authored about 70 scientific papers, over 40 reports and several books on environmental history, palaeolimnology and diatom taxonomy.

Elizabeth (Liz) graduated in Botany from University College of North Wales, Bangor and in 1965 began an M.Sc. on diatoms in Blea Tarn post-glacial sediments with Dr J.W.G. Lund at the Freshwater Biological Association. This was an early introduction to the Fritsch Collection. Finding Asterionella present in the early post-glacial lake refuted the Pearsall theory that post-glacial oligotrophy led naturally to eutrophy. Following a research year at the Limnological Research Center in the University of Minnesota she returned to the FBA in 1968 to join the new palaeolimnology group headed by Dr Winifred Pennington (Mrs Tutin). Whilst on FBA staff her PhD thesis was on the environmental history of some lochs in Sutherland as an external student of Leicester University.

Diatoms in the historical environment and man's influence on landscape led to studies of diatom taxonomy, morphology and distribution, and collaboration in various environmental history studies including those on eutrophication and acid rain studies. Studies included the use of  electron microscopes when they first became more general. Publications have varied from the Miocene to the present and from new species to environmental history interpretation in the English Lake District and elsewhere. With Horace Barber, an amateur diatomist, she produced the FBA book on Diatoms Morphology in 1980. FBA staff were transferred to what is now the Centre for Ecology and Hydrology (NERC) in 1986.

Liz took early retirement from CEH in 1996 and has held an Honorary Fellowship with the FBA since that time. On the official retirement of Dr John Lund she became responsible for the Fritsch Collection of Algal Illustrations and acted as John Lund's deputy until becoming Curator in 2004.

She was a founder of the British Diatomists, an informal group to bring together academics, amateurs and students, a founder member of the International Society for Diatom Research and its Treasurer for 6 years. She is a member of the British Phycological Society, the Queckett Microscopical Club, The Quaternary Association and Cumbria Wildlife Trust.

A member of Brathay Exploration group and one of its first women leaders, she edited The Tarns of the Central Lake District combining the studies of both the FBA and Brathay.

Her other interests include genealogy and local history, and U3A studies. She has been Chairman of The Arthur Ransome Society and a fund raiser for the RNLI.
