John Archibald Purves

John Archibald Purves FRSE (8 July 187011 April 1952) was an English electrical engineer best remembered as inventor of the Dynasphere. However, his biggest contribution was in the field of electricity supply.

Possibly owing to the error appearing throughout a May 1932 Popular Science magazine article on the Dynasphere, J. A. Purves' initials, in sources about his Dynasphere, are sometimes given as "J. H."
