Isidore Salmon served his apprenticeship in the kitchens of the Hotel Bristol, London. He subsequently worked for Lyons and was in charge of catering at the
Olympia Exhibition Centre and the
Crystal Palace. In 1907, he was elected to the
London County Council as a
Municipal Reform Party councillor. Initially he represented
Islington West, then
Hammersmith from 1910. He remained a member of the council until 1925, and was vice-chairman in 1924–25. Later that day he presided over a grand luncheon to celebrate the hotel's opening. From March 1938 until his death, Salmon held the office of honorary catering adviser to the
British Army. He spent seven years as vice-president of the
Board of Deputies of British Jews and was actively involved in a number of Jewish charities in London. He was instrumental in persuading
Viscount Rothermere to withdraw the
Daily Mail's support for Oswald Mosley and the
British Union of Fascists in 1934, by threatening to remove advertising for Lyons from the paper. ==Personal life==
