Sir Sigismund Ferdinand Mendl  (2 December 1866 – 17 July 1945) was a British Liberal Party politician and businessman.

Early life 
Mendl was born in Kensington, the son of Czech-born grain importer and shipowner Ferdinand and Jeanette Rachel Mendl. He was educated at Harrow School and University College, Oxford, graduating with second-class honours in Jurisprudence, and was called to the bar at the Inner Temple. Mendl was a grain importer, like his father, and served as president of the London Corn Trade Association from 1909 to 1912 and again from 1915 to 1919, and on the Royal Commission on Wheat Supplies until 1920. From 1915 to 1918, he was also a member of the War Office Advisory Committee on Army Contracts. Mendl was the first chair of Decca Records, a company that his grandson, Hugh, worked for. He was appointed Vice President of the World Services Group in 1938.

Political career 
Mendl was the Liberal MP for Plymouth from 1898 to 1900, having unsuccessfully contested the seat in 1895 and the Isle of Wight constituency in 1892. During his election campaign in Plymouth, the Chief Rabbi Hermann Adler urged Jewish voters in Plymouth to vote for the non-Jewish Conservative candidate over Mendl, who was Jewish. From 1915 to 1918, Mendl served on the War Office Advisory Committee on Army Contracts. Mendl was knighted in 1918.

Personal life 
He married Frances Moses in 1888, with whom he had two sons.  His younger brother, Charles Mendl, was a diplomat. He died on 17 July 1945. His funeral was held on 20 July at Golders Green Crematorium.
