Slater was born in Hampstead on 24 February 1879 to John Slater and his wife Mary, née Wilkins. She had two sisters, including geologist Ida Slater.[1]

She studied at Newnham College, Cambridge from 1899 to 1903, and then received a Bathurst studentship to continue her studies in 1903–5.[2] She worked on thorium at the Cavendish Laboratory under J. J. Thomson.[3] She established that the decay products of thorium volatised at different temperatures, and showed that thorium and radium emanations emitted delta rays.[1]

She received her BSc in chemistry from the University of London in 1902,[4] as Cambridge was not awarding degrees to women at the time, and was one of the first women to receive a doctorate in science at the University of London in 1906.[5]

After teaching at Cheltenham Ladies' College from 1909 to 1913, she returned to Newnham as a lecturer in physic and chemistry from 1914 to 1926.[1]

During World War I she worked part-time as a nurse. In 1918, she worked as a radiologist at a British military hospital in France.[1][6]

In June 1926, she married Harold Baily.[7] She served on school care committees and on the Council of Unitarian and Free Christian Churches. She served two terms as mayor of Hampstead in 1930–1 and 1931–2.[8]  

She died on 25 December 1961.[1]
