GRIMWADE, Leonard Lumsden (c. 1863-1931), pottery manufacturer, Stoke upon Trent.

Leonard Grimwade was born in Ipswich about 1863, the son of Richard Grimwade. He began his business life with his uncle as a dry salter in Ipswich. He came to the Potteries as a modeller but quickly moved to manufacturing. 

He was joined by his brother, Sydney, by 1886, and worked the Winton Pottery. The style became Grimwade's Ltd. in March 1900.

Leonard Grimwade went for a time to Australia but returned to the Potteries.

In association with Brittain's, of Cheddleton (the paper manufacturers), he devised a thin printing tissue with a detachable backing, known as 'Duplex' paper, which facilitated the handling of lithographic sheets. The invention helped to make the litho process commercially viable. 

He is also credited with installing the first continuous process kiln, in 1901. In this process, known as the Climax kiln, the ware was packed into iron cages on wheels. 

A serious fire at the Winton factory in 1916 led to Leonard Grimwade's proposing that Stoke on Trent should have at least three motor fire engines. 

A Liberal free-trader Leonard Grimwade was elected to Stoke upon Trent council and was also appointed to the local magistrates' bench. He was secretary of the Potteries Association for the Promotion of Federation, founded in 1907, and published 160 favourable replies to a circular letter to leaders of trade and industry in his Book of Opinions. Questioned by counsel for Fenton during the passage of the federation bill through Parliament and asked where he lived Leonard Grimwade replied "I sleep in Wolstanton but I live in the Potteries". He unsuccessfully contested the parliamentary election in Hanley as a Liberal in 1918. He was a member of King Street, Newcastle, Congregational church. 

He modified his free-trade views to some extent during the First World War, by which time his five factories employed 1,000 people. In December 1917 he printed a message from the prime minister asking for economy in consumption of food on reduced sized butter dishes, milk jugs and plates, which sold at one shilling each.

He married twice and had two sons and two daughters. His first wife, Marion, was elcted to the Stoke Board of Guardians in 1897. He was killed in a road accident on 26 January 1931 and was buried in Hartshill cemetery.
