He made a number of visits to the United States. In 1947 he became professor of mathematical statistics at the School of Mathematics at the University of Manchester where he not only developed his interests in epidemiology but also served as an able and active administrator. In 1960, he took up the chair of statistics at University College, London before serving the last eight years of his academic life as professor of biomathematics at the University of Oxford. He retired in 1975. After his retirement Bartlett remained active in statistics, visiting the Institute of Advanced Studies at the Australian National University several times. He had married Sheila, daughter of C. E. Chapman, in 1957, the couple parenting a daughter. Bartlett died in Exmouth, Devon. Bartlett is known for Bartlett's method for estimating power spectra and Bartlett's test for homoscedasticity.
