After postgraduate work at Cambridge Corner went to Singapore as Assistant Director of the Botanic Gardens, a post he held 1929-1946. He then went to Brazil to work for UNESCO on the Hylean Amazon project before returning to Cambridge, subsequently becoming Professor of Tropical Botany. Corner was a colleague of Hill's at Cambridge in the 1920s and Hill stayed with Corner during his visit to Singapore and the Dutch East Indies in 1932 (see GBR/0012/MS Add.9267/H.2-GBR/0012/MS Add.9267/H.9). The correspondence is chiefly personal news, conducted on Corner's part in very friendly terms, and to a lesser extent the progress of Corner's botanical research. For photographs found with the correspondence see GBR/0012/MS Add.9267/A.77 and GBR/0012/MS Add.9267/A.78.
