Thomas Holmes Blakesley
Thomas Holmes Blakesley (born July 8, 1847 in Ware (Hertfordshire) , † February 13, 1929 in London ) was a British mathematician and practical scientist .
The son of Rev. Joseph Williams Blakesley (1808-1885) and Margaret Wilson Holmes graduated from the University of Cambridge in 1869 ( 34th Wrangler , 1869), he made an apprenticeship in civil engineering (1872 Masters in Cambridge) and then became a freelance consultant.
1872-75 he went to Ceylon on behalf of the government to construct irrigation there.
He was interested in electrical transmission, especially telephony and telegraphy. He was associated with William Henry Preece and John Ambrose Fleming . A problem at the time was the time delay caused by self-induction over long distances such as in submarine cables. In 1884 he received a patent for an apparatus built by JT Mair & Co. London for measuring the time constants of electrical circuits.
From 1885 he was a lecturer in mathematics and physics at the Royal Naval College .
