Description:A waist-length portrait of the subject facing front and resting his hands on what appears to be a stone wall. He is wearing a grey double-breated suit over a white shirt and red four-in-hand. His head is turned slightly to his right and his brown eyes look to the distance and to the left of the viewer. On the hills behind him the observatory can be seen above his left shoulder.
History of Work:In 1935 Muriel E. Mussells married Carl K. Seyfert. Portrait was completed in Nashville, Tennessee.
Notes:Dr. Carl K. Seyfert - February 11, 1911, Cleveland, Ohio June 13, 1960, Nashville, Tennessee. In 1935 he married Muriel E. Mussells; they had a son, Carl Keenan, Jr., and a daughter, Gail Carol.

Carl Keenan Seyfert was an American astronomer. He is best known for his 1943 research paper on high-excitation line emission from the centers of some spiral galaxies, which are named Seyfert galaxies after him. Seyfert's Sextet, a group of galaxies, is also named after him.

Seyfert grew up in Cleveland, then attended Harvard University, starting in 1929. He earned his B.S. degree there, and then his M.S. degree (1933). In 1936 he received his Ph.D. in astronomy. His thesis was ""Studies of the External Galaxies"", supervised by Harlow Shapley. The thesis dealt with colors and magnitudes of galaxies.

In 1936 he joined the staff of the new McDonald Observatory in Texas, where he helped get the observatory started. He stayed until 1940, working with Daniel M. Popper on the properties of faint B stars and continuing his work on colors in spiral galaxies.

In 1940 he went to Mt. Wilson Observatory as a fellow with the National Research Council. He stayed until 1942, studying a class of active galaxies now called Seyfert galaxies. In 1942 he returned to Cleveland, at the Case Institute, where he taught navigation to military personnel and participated in secret military research. He also carried out some astronomical research at the Warner and Swasey Observatory of the Case Institute.

In 1946 he joined the faculty of Vanderbilt University in Nashville, Tennessee. The astronomy program at Vanderbilt was very small at the time. The university had only a small observatory, equipped with a 6-inch (150 mm) refractor, and only a modest teaching program.

Seyfert worked diligently to improve the teaching program and to raise funds to build a new observatory. Within a few years, he had obtained significant public support from the Nashville community. As the result, the Arthur J. Dyer Observatory with its 24-inch (610 mm) reflector was completed in December 1953. Seyfert became director of the new observatory, a position he held until his death. He died in an automobile accident in Nashville on June 13, 1960. He was 49 years old.

Carl Seyfert published many papers in the astronomical literature, on a wide variety of topics in stellar and galactic astronomy, as well as on observing methods and instrumentation.

In 1943 he published a paper on galaxies with bright nuclei that emit light with emission line spectra with characteristically broadened emission lines. The prototype example is Messier 77 (NGC 1068). It is this class of galaxies that is now known as Seyfert galaxies, in his honor.,br>
During his time at the Case Institute, he and Nassau obtained the first good color images of nebulae and stellar spectra. In 1951 he observed and described a group of galaxies around NGC 6027, now known as Seyfert's Sextet. He was an active innovator in instrumentation, being involved in new techniques such as the astronomical use of photomultiplier tubes and television techniques, and electronically controlled telescope drives.

A crater on the moon was named in his honor (Seyfert, 29.1N, 114.6E, 110 km diameter) in 1970. The 24-inch (610 mm) telescope at Dyer Observatory was renamed for him.
