Watters, Leon Laizer


WATTERS, LEON LAIZER (1877–1967), U.S. scientist, teacher, writer, and communal leader. Watters was born in Salt Lake City, Utah. After teaching chemistry at Columbia University (1898–1900) and the University of Cincinnati (1901–2), he became a food and drugs investigator for the City of New York and presented papers on that subject before the American Association for Advancement of Science. Watters developed a method for sterilizing catgut used as sutures in surgery. He founded the Watters Laboratories and Hospital Supply Company, which he later sold to the Air Reduction Company (1948). During World War i he built the first portable disinfectors for the U.S. Army and Navy. In World War ii he designed a mobile hospital unit that was used in North Africa by the British. A civic-minded scientist, Watters was a founder and president of the Utah Club of New York, head of the advisory committee of Cooper Union, and a member of the Chemists Club of New York. At the suggestion of his friend Albert Einstein, he endowed the Watters Memorial Research Laboratory for experimental research in pure physics at the California Institute of Technology and established scholarships and students' loan funds at the University of Utah. Active in Jewish life, Watters was chairman of the New York section of the Jewish Welfare Board during World War i. He served at one time as vice president of the Hebrew Technical Institute and as treasurer of the New York ymha. Watters' nontechnical writings included Pioneer Jews of Utah (1952); his papers are at the American Jewish Archives at Hebrew Union College in Cincinnati, Ohio.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
