Editing Karl Gordon Henize (section)

==Experience==

Henize was an observer for the University of Michigan Observatory from 1948 to 1951, stationed at the [[Lamont–Hussey Observatory]] in [[Bloemfontein]], [[Union of South Africa]]. While there, he conducted an objective-prism spectroscopic survey of the southern sky for stars and nebulae showing emission lines of [[hydrogen]].

In 1954 he became a Carnegie post-doctoral fellow at the [[Mount Wilson Observatory]] in [[Pasadena, California]], and conducted spectroscopic and photometric studies of emission-line stars and nebulae. From 1956 to 1959, he served as a senior [[astronomer]] at the [[Smithsonian Astrophysical Observatory]]. He was in charge of photographic [[satellite tracking station]]s for the satellite tracking program and responsible for the establishment and operation of a global network of 12 stations for photographic tracking of artificial Earth satellites.<ref>{{cite web|url=https://siarchives.si.edu/collections/siris_arc_216832|title=Record Unit 263, Smithsonian Astrophysical Observatory, Satellite Tracking Program, Satellite Tracking Station Records, 1953–1968|publisher=Smithsonian Institution Archives|access-date=July 27, 2019}}</ref>

Henize was appointed [[associate professor]] in [[Northwestern University]]'s Department of [[Astronomy]] in 1959 and was awarded a professorship in 1964. In addition to teaching, he conducted research on planetary [[nebulae]], [[peculiar emission-line star]]s, [[S-type star]]s, and [[T-association]]s. During 1961 and 1962, he was a guest observer at [[Mount Stromlo Observatory]] in [[Canberra]], [[Australia]], where he used instruments ranging from the Uppsala 20/26-inch schmidt to the 74-inch parabolic reflector.

Henize also engaged in studies of [[ultraviolet]] optical systems and astronomical programs suited to the crewed space flight program. He became principal investigator of [[experiment S-013]] which obtained [[ultraviolet stellar spectra]] during the [[Project Gemini|Gemini]] 10, 11, and 12 flights.{{sfn|Shayler|Burgess|2007|p=513}} He also became principal investigator of experiment S-019 in which a 6-inch aperture objective-prism spectrograph was used on [[Skylab]] to obtain ultraviolet spectra of faint stars.

From 1974 to 1978 Henize chaired the [[NASA Facility Definition Team]] for [[STARLAB]], a proposed 1-meter UV telescope for [[Spacelab]]. From 1978 to 1980 he chaired the NASA Working Group for the [[Spacelab Wide-Angle Telescope]]. Since 1979 he had been the chairman of the International Astronomical Union Working Group for Space Schmidt Surveys and was one of the leaders in proposing the use of a 1-meter (3&nbsp;ft) all-reflecting Schmidt telescope to carry out a deep full-sky survey in far-ultraviolet wavelengths.

He authored or co-authored 70 [[scientific publications]] dealing with astronomy research.<ref name=nasabio1>{{cite web|url=https://www.nasa.gov/sites/default/files/atoms/files/henize_karl.pdf|title=Biographical Data|access-date=March 12, 2021|publisher=NASA |date=March 2007}}</ref>
