In 1938, while at New York University, I applied for a grant from the Research Corporation to purchase a Dobson Ozone Spectrophotometer from England to start routine measurements of ozone in the upper atmosphere in the United States.
Dr. G.M.B. Dobson of Oxford personally supervised and calibrated the instrument prior to shipment. A New York newspaper of that time erroneously stated, “Professor Athelstan Spilhaus, of New York University, has invented a device for measuring ozone of the atmosphere. In Britain, Professor G.M.B. Dobson also has developed such instruments.”
