Made an extensive collection of Coleoptera from the home counties which was divided in 1981 between North Hertfordshire Museum at Baldock (later moved to the natural history unit at Hitchin) the Horniman Museum and the NHM. All manuscript and related material is housed at Hitchin. Hall was in contact with many of the Coleopterists of his day and the collection which includes many specimens from Bookham collected by him in the 1960s-70s,includes material from A.J.Barnes (see p. 142; the bulk of his collection of c.4,000 specimens at least), E.C.Bedwell, Edmunds, E.G.Elliman, Hadfield, James Hignett, Edward Shepherd, C.E.Stott, G.M.Ashe, Tomlin, G.B.Walsh (many specimens), J.J.Walker, E.A.Newbery, F.D.Buck, K.M.Guichard, M.A.Park, Batten, H.D.Swain, Chaney, C.H.W.Pugh, May, R.D.Weal, and F.J.Coulson. (I am grateful to Trevor James for this information). There is an obituary of Hall in London Naturalist, 58, 1978, which I have not seen. (MD 3/03. 1/22)
