Hertha Doreck

Hertha Sieverts-Doreck, née Sieverts (15 July 1889 – 30 March 1991), was a German paleontologist who studied and published her research about the marine animals called Cretaceous Crinoids. She often published her research under the name Hertha Sieverts-Doreck.

Life
Hertha Walburga Doris Sieverts-Doreck was born in Völklingen, German Empire, in 1899, the eldest of three daughters born to a chemist father.

Education
She trained as a teacher for schools in Prussia, but she became interested in mathematics and the natural sciences. Doreck focused on zoology, paleontology and geology during her time at the University of Berlin and she researched Cretaceous Crinoids for her dissertation, which she completed under the supervision of Josef Felix Pompeckj in 1927.

Research
After she was only able to find a series of short-term positions, she was finally hired at the Institute for Applied Geology in Bonn at a very low salary in 1930. Although she mostly worked as a personal assistant to J. Wanner, she was allowed to work with the fossil collection. After five years, she got a training opportunity at the National Prussian Geological Institute in Berlin and was hired there in 1936 in the role of a scientific assistant. This job entailed mapping and fieldwork; it was unusual for a woman to perform such work at that time.

Private research
Her public employment ended in 1936 when she married Walter Doreck and assumed the role of private-researcher. The couple had two daughters, yet Hertha continued her active research efforts, publishing her results on Crinoids in the journal Zentralblatt for fourteen years.

R.C. Moore invited Doreck to his facilities in Lawrence, Kansas, where she assumed the role of the 'German Crinoid Expert.' According to Ogilvie, "She had devised a system of classification for Mesozoic Crinoids that, although never published, was and still is the basis for the systematics of this group. During the last years of her research, Doreck turned to the systematics of the Holothuroideans."

When her husband became seriously ill, Doreck took care of him until his death in 1972. She died on 30 March 1991.

Honors
The Paleontological Society named Doreck an honorary member in 1987 because of her contributions to the field.
