Description
Cold cathode glass x-ray tube designed by Henry Lyman Saÿen and manufactured by Queen & Co. in Philadelphia.
The form, manufactured between 1897 and 1905, was the first that automatically regulated the gas pressure so that the output and quality of x-rays could be maintained. It won the John Scott Medal, from the Franklin Institute, in 1898.
A label on this example reads "3808." Two connectors are missing. Henry Lyman Saÿen was also a pioneer of American abstract art.
