Gustave Lyon

Gustave Lyon (19 November 1857 – 12 January 1936) was a French piano maker, acoustician and inventor.

[1][2] Auguste Wolff, director of the piano maker Pleyel et Cie, offered him a place in the company.

[2] In the First World War, although not obliged to take part, Lyon was commander of artillery on the east coast of the Cotentin Peninsula; later, as deputy to the director of land artillery, he organised the defence of Cherbourg against aircraft.

During this time he invented instruments for locating aircraft, and studied ballistics.

He also helped to preserve important buildings which had been condemned for their poor acoustics.
