Rowland (Henry Augustus) papers, 1793-1970

Correspondence, research notebooks, lab notes, patents, lectures, writings, reprints, and financial material relating to Henry Rowland's work as a physicist and an entrepreneur. Rowland's student and teaching papers are strong in documenting the experimental processes of physics and engineering training in the late nineteenth century both in Europe and the United States. This includes material on the organization and suplying of the Physical Laboratory at Hopkins. His notebooks and lab data cover research on acoustics, diffraction gratings, electricity, electromagnetism, hydroelectric power, optics, and x-rays. His own research papers are supplemented by Rowland's vast (56 volume) reprint collection. Rowland's work evaluating machinery for the Niagra Falls hydroelectric project (1892-1901) is well-represented as are the records and research for his Rowland Multiplex Telegraph Company (1898-1905)
