GEORGE ADDY was born in Leeds on 15th April 1857, being the son of Samuel Addy, who built Leeds Town Hall.
As a young man he excelled in athletic sports, and gained many prizes, medals, and cups, etc.
In the early "Nineties" he established a business in Sheffield as a consulting engineer, to which that of steel manufacturer was afterwards added.
In 1890 he read a Paper before this Institution on "Milling Cutters," which was recognized as a standard work on cutting metal by revolving cutters. He devoted much attention to labour-saving appliances, and made a speciality of the heavy machine-tools used by shipbuilders, locomotive engineers, and boiler makers.
Mr. Addy took a keen interest in the affairs of Sheffield, and was a Member of the City Council from 1902 to 1905 and from 1916 till the time of his death.
In 1917 he was instrumental in forming a "Merchant Section" of the Sheffield Chamber of Commerce and during the War he rendered patriotic service in a variety of ways, not the least useful being the example he set as a voluntary tram-driver.
During the last few years he had suffered much from bad health, and had undergone a serious operation in 1920, but had recovered sufficiently to conduct an election campaign.
His death, however, took place unexpectedly on 20th December 1922, in his sixty-sixth year.
He became a Member of this Institution in 1889.
