Background
Leslie was born to Frederick Leslie, a coal miner and bookseller, and Elizabeth Dickinson.
assistant chemist lecturer school teacher
Leslie was born to Frederick Leslie, a coal miner and bookseller, and Elizabeth Dickinson.
She was educated in Leeds, graduating from a high school in 1905. She received her Bachelor of Science in chemistry with honours from the University of Leeds in 1908, and her master"s degree in 1909 for her work on the kinetics of iodination of acetone.
From 1920 until her death Leslie was a Fellow of the Royal Society of Chemistry. After that she worked as a research assistant to Marie Curie in Paris (1909–1911) and wrote several articles in French on extraction of new elements from thorium and their properties. Upon recommendation from Curie, she then moved to Manchester to work on the properties of thorium and actinium with Ernest Rutherford (1911–1912).
After leaving Manchester she worked as a high school teacher in West Hartlepool (1912–1913) and as an assistant lecturer and demonstrator in chemistry at the University College in Bangor, Wales (1914–1915).
During World War I Leslie worked on large-scale manufacture of explosives in Liverpool. Women were held in low esteem in science and engineering in those years.
Thus both her Bangor and Liverpool appointments were unusual and could be explained by the shortage of men during the war. She had lost her job in explosives research in 1917 upon return of male engineers from the front.
In 1918 Leslie was awarded a doctoral degree by the University of Leeds for her combined work on thorium and explosives.
The same year she became a demonstrator in chemistry at Leeds and in 1928 a full lecturer in physical chemistry. During those years her research mostly focused on the chemistry of synthetic dyes. Back in 1920 she became Fellow of the Royal Society of Chemistry.
In 1923 Leslie married Alfred Hamilton Burr, a chemist at Salford.
She died four years later on 3 July 1937.
