Warren S. Johnson : ウィキペディア英語版 | Warren S. Johnson Warren Seymour Johnson was a college professor who was frustrated by his inability to regulate individual classroom temperatures. His multi-zone pneumatic control system solved the problem. Johnson’s system for temperature regulation was adopted worldwide for office buildings, schools, hospitals, and hotels – essentially any large building with multiple rooms that required temperature regulation. To manufacture and market his system, Johnson established the Johnson Electric Service Company which eventually became Johnson Controls. ==Early Life== Johnson was born in Leicester, Vermont on November 6, 1847. His family moved to Wisconsin three years later, eventually settling in Menomonie. It appears that he had only limited formal educational training – but supplemented his knowledge with self-study of scientific subjects. He worked for a time as a printer, surveyor, schoolteacher, principal and school superintendent. In 1876 he obtained a teaching position at the State Normal School in Whitewater – now known as the University of Wisconsin–Whitewater. Five years later he was named professor of natural science.〔"Prof. Johnson”, Historical Sketches from the First Quarter Century of State Normal School, Whitewater, Wisconsin, 1893, p. 125-6.〕
