Paul’s Technical and Scientific Work
Paul was establishing his career as an electrical instrument maker when he was drawn into moving pictures in 1894. Despite the rapid growth of the film business from 1896, he maintained his instrument manufacturing and in 1903 secured a lasting success with the Unipivot galvanometer, versions of which continued in production for nearly fifty years. His instruments won medals at major exhibitions in America and Belgium, and he opened an office in New York in 1911. During World War I, he contributed to aircraft height-finding and magnetic mine detection, then merged his company with Cambridge Scientific instruments in 1919, serving on the joint company’s board until his death. Although retired from technical design, he worked with Sir William Bragg in 1934 to create the Bragg-Paul Pulsator, a portable ventilator designed to help sufferers from respiratory illness, which saved many lives during polio and diphtheria outbreaks in the later 1930s.
