Captain Cyril Diver, C.B., C.B.E., (1892 – 17 February 1969), was a civil servant and amateur naturalist.
[1] In the 1930s he performed a systematic survey of the varied ecosystems of Studland, Dorset.
In May 1940 the House of Commons appointed its "Miss K Midwinter" as the first woman to be a clerk.
She was initially placed as an assistant to "Captain Diver", but she went on to have her own committee in the following year.
[3] Between 2012 and 2015, the National Trust ran a citizen science project named after Cyril – the Cyril Diver Project that was designed to carry out a comprehensive ecological survey of the Studland peninsula in a similar manner to Diver's original study.
