Louis Philip Brennan was born on the 28th January 1852
at Main Street, Castlebar, Co. Mayo, the son of a hardware merchant, Thomas Brennan, and his wife, Bridget. Thomas and Bridget
Brennan sold their business in Castlebar in 1861, and emigrated with their youngest son, nine year old Louis, to Melbourne,
Australia. After his primary education he went to Joel Ease's Technical College, in Collingwood, Melbourne.
took up employment with an engineering firm and continued his inventive experiments. His first major invention was the steerable
torpedo, for which he was granted a patent. In 1880 he accepted an offer of £110,000 from the British Government for
the “exclusive rights” to his invention and an invitation to go to England. Brennan became manager of the Government
Torpedo Manufacturing Plant, at Gillingham, Kent, which manufactured his own torpedo, from 1880 to 1896.
1916 to 1919 Brennan served in the munitions inventions department. From 1919 to 1926 he was engaged by the air ministry in
aircraft research work at the Royal Aircraft Establishment, Farnborough, and gave much time to the invention of a helicopter.
The government spent a large sum of money on it, but in 1926 the air ministry gave up working on it, much to Brennan's disappointment.
While on holiday in Montreux, Switzerland, Louis Brennan was knocked down by a car on 26th December 1931, and died
as a result of the injuries received on 17th January 1932 in Montreux.
