Reverend Robert Ashington Bullen FLS, FGS, FZS, FRAS (11 June 1850 – 14 August 1912) was an Anglican priest, a geologist and an authority on mollusca.

On leaving school it was planned that he should join the Civil Service but a change in his circumstances led him becoming a schoolmaster while at the same time attending the University of London where he took his BA in 1873.

[3] It was at Shoreham that he befriended Sir Joseph Prestwich, who persuaded Bullen to carry out a series of researches in locations where fossil land and freshwater mollusca could be found, and in particular those connected with the remains of early Man.

He devoted much time to the work of the various scientific societies to which he had become attached, and in travelling in France, Italy, Spain, and elsewhere leading to his papers on the fossil mollusca of Mallorca, Catalonia and Bermuda, which were of particular interest.

The death of his second daughter Evelyn Margaret Bullen in February 1910 affected him deeply and as a result he moved to Hilden Manor, Tonbridge.
