Florence Petty (1 December 1870 – 18 November 1948) was a Scottish cookery writer and broadcaster. During the 1910s, in the socially deprived area of Somers Town, north west London, Petty ran cookery demonstrations to working-class women to get them in the habit of cooking inexpensive and nutritious foods. Much of the instruction was done in the women's homes, allowing her to use their own limited equipment and utensils.
