A collection of nineteen scholarly offprints

Cambridge, Philadelphia and London, 1902. O. W. Richardson (1879-1959) was a British physicist who won the Nobel Prize in Physics in 1928 for his work on thermionic emission, which led to Richardson's law. He was professor at Princeton University from 1906 to 1913, and returned to the UK in 1914 to become Wheatstone Professor of Physics at King's College, London, where he was later made director of research. He was knighted in 1939. Note on a method for determining the concentration of hydrogen ions in solution, by H. O. Jones and O. W.
