This text is not an autobiography or a memoirs, but the proofs and works of an extraordinary man who held doctorates from John Hopkins University, Yale and Princeton. After his death in 1901, Johns Hopkins University chose to honor their colleague by publishing his life's work. Included in this book are the ideas, proofs, addresses, illustrations and comments of Henry Augustus Rowland. Henry A. Ro...

-1901)was pronounced "the foremost scientist America has yet produced" by the president of the National Academy of Sciences in 1924, and achieved high recognition as an expert on electricityRowland's research helped to demonstrate that electric currents are the source of magnetic fields, to determine the value of the Ohm (a unit of electrical resistance), and to show that specific heat (the ability of a substance of absorb heat as measured by the increase in temperature per unit of heat absorbed) varies with temperature. The first professor of physics at Johns Hopkins University, he is best remembered for the invention and ruling of concave spectral grating, an instrument of unprecedented precision and ease of use. At the Paris Exposition of 1890 he won grand prize for spectral grating and revision of the solar spectrum.He worked in both mathematical and experimental physics and had significant success in precise measurements of physical constants. He designed many types of measuring instruments, several of which were adopted for commercial use. He was elected to the National Academy of Sciences, to the Royal Society of London and to the French Academy of Sciences. In 1899, Rowland became the first president of the American Physical Society.Rowland's contributions to experimental physics were enhanced by his understanding of practical mechanics, his mathematical aptitude, and his manual dexterity.
