Leslie was born on November 15, 1787 in Philadelphia, Pennsylvania to Lydia Baker and Robert Leslie, both originally from Maryland. Her father, a clock and watchmaker, was a friend of Benjamin Franklin and Thomas Jefferson, according to Eliza. The family moved to England in 1793 when Leslie was five years old for about six years. She was the eldest of five children. Two of her siblings, Charles Robert Leslie, who lived in London, and Anna Leslie, were artists. Her brother Thomas Jefferson Leslie graduated from West Point and her other sister, Martha “Patty,” married the book publisherHenry Charles Carey. Following her father’s death in 1803, her mother operated a series of boarding houses. They moved from their home on High Street to a boarding house on South Sixth Street, then Spruce Street, and, finally, to 1 Minor for the last two years of her mother’s life before she died in 1824. Leslie attended the cooking school of the famed Mrs. Goodfellow for two terms, and her first book was based on notes she had taken of Goodfellow’s class recipes, although in the introduction she insisted the recipes were "original, and have been used by the author and many of her friends with uniform success." Seventy-Five Receipts for Pastry, Cakes, and Sweetmeats first published in 1828, became a success and went through eleven editions until 1839.
Career
Leslie’s Directions for Cookery, in its Various Branches, sold at least 150,000 copies and stayed in print into the 1890s, making it the most popular cookbook of the century. It was a generalized work, written to appeal to all classes and to city or rural dwellers from all regions. Some of her nine cookbooks were more specialized. Using the French she learned as a child, Leslie translated French recipes for Domestic French Cookery and wrote an entire book on cornmeal recipes, The Indian Meal Book. She was a prolific writer of fiction and nonfiction works for juveniles and adults. Almost yearly, between 1836-1845, Leslie edited an annual gift book called The Gift: A Christmas and New Year’s Present, with contributions from Edgar Allan Poe, Henry Wadsworth Longfellow, and Ralph Waldo Emerson. She also contributed to Godey’s Lady’s Book, Graham’s Magazine, Saturday Gazette, and Saturday Evening Post.
