Alfred Edwin Howard Tutton (22 August 1864 – 14 July 1938) was a British inspector of schools who was a crystallographer in his spare time.
Educated at the National School, Edgeley, he worked for a while as a town clerk and later as a medical officer at Stockport.
He attended evening classes in chemistry at Owens College with lectures by Sir Henry Roscoe.
A scholarship allowed him to study under Percy Faraday Frankland, Thomas Edward Thorpe, John Wesley Judd and Arthur William Rucker at the Royal College of Science in London for three years.
Using his interferometric technique, he was able to verify the use of the wavelength of a specific spectral line as a way of standardizing the imperial yard in 1930.
