Henry Augustus Rowland (1848-1901) was one of the most important figures in the founding of modern physics in the U.S. A principal founder & first pres. of the Am. Physical Soc., he is best known for his invention of the concave spectral grating for which he won a gold medal & grand prize at the 1890 Paris Exposition. A grad. of Rensselaer Polytechnic Institute in civil engineering, Rowland was prof. of physics at Johns Hopkins U., where he had the principal part in forming the first school of Am. physicists to be professionally trained in the U.S. In this vol., George Kean Sweetnam, using Rowland's papers & those of his colleagues & students, has written the first scholarly exposition of Rowland's work.
