Rupert Wildt

Died 9 Jan 1976 at age 70 (born 25 Jun 1905).German-American astronomer who studied atmospheres of planets. He identified (1932) certain absorption bands (observed by Slipher) in the spectra of Jupiter and the outer planets as indicative of ammonia and methane as minor components of these planets which are primarily composed of hydrogen and helium. He speculated (1937) that droplets of formaldehyde formed the clouds of Venus, since water was not detected. (In fact, surface water is absent on Venus, but the clouds do contain water with sulphur and sulphuric acid.) In 1939, he realized the importance of the negative hydrogen ion for stellar opacity. By the 1940s, he proposed the greenhouse theory to explain how atmospheric gases produced unexpectedly high temperatures of Venus.
