Frank Hope-Jones

Frank himself moved into the field of electric clocks and together with George Bennett Bowell founded the Synchronome business in 1895, the same year that the pair secured an important patent, embodying the 'Synchronome switch'.

[2] Following an aborted plan to float the firm on the London Stock Exchange in 1899, Bowell left to pursue his own interests.

William Hamilton Shortt, a gifted railway engineer, joined the Synchronome Company in 1912 as a director, contributing towards efforts to create precision pendulum clocks.

[4] In 1921, Hope-Jones orchestrated a petition from the Wireless Society of London to the Postmaster General, urging the authorities to permit renewed wireless transmissions, following a wartime ban, and this document was pivotal in securing government agreed to permit public transmissions by Marconi and later by the BBC from its 2LO radio station.

In 1924, legislation made Daylight Saving Time permanent, as opposed to a temporary measure, first introduced in the war.

He reworked and updated the material significantly to produce Electrical Timekeeping (NAG Press) in 1940, which was again revised for a new edition in 1949.
