Clarence Weston Hansell (January 20, 1898 – c. 1967) was an American research engineer who pioneered investigation into the biological effects of ion air. He was granted over 300 US patents, including, in the 1930s, a precursor to the modern ink jet printer that could print 750 words a minute, its data received via radio telegraph. Only Thomas Edison held more patents.
