Rosalind Wulzen

[edit]

Rosalind Wulzen (b. 1886)[1] was an American physiologist, known for her discovery of the "Wulzen anti-stiffness factor."

Biography

[edit]

Early life

[edit]

Born in Oakland, California,

Education

[edit]

Wulzen attended the University of California, Berkeley, graduating with degrees in Physiology and Anatomy (B.S. 1904; M.S. 1910; Ph.D. 1914).[2] Her master's thesis was entitled, "On the mechanism of cytolysis in paramecium,"[3] and her doctoral thesis was entitled, "The pituitary gland in its relationship to the early period of growth in birds."[4]

As a student, Wulzen was the Secretary and President of Sigma Xu, as well as the President of Phi Beta Kappa.[2]

Teaching

[edit]

Between receiving her bachelor's degree and beginning her master's degree, Wulzen was a science teacher at Chino High School in California from 1904-1905 and at Martinez High School in California from 1905-1906.[5] Then, while completing her doctoral degree, Wulzen was an Assistant Professor of Biology at Mills College from 1909-1914, teaching courses on Elementary Biology, Biology Laboratory, Bacteriology, Human Anatomy. Physiology, Physiology Laboratory, Advanced Physiology, and Microscopical Techniques.[2]

Upon graduating with her Ph.D. in 1914, Wulzen became an Instructor in Physiology at the University of California, Berkeley, teaching the courses of Introductory Biology, Experimental Biology, and Physiology.[4] She remained a professor here for fourteen years.[2]

In 1928, Wulzen became an Instructor and Assistant Professor in the Department of Animal Biology at the University of Oregon.[2] Here, she continued her research on the pituitary gland and began studying planarian worms.

Wulzen took a full-time position as a professor at Oregon State University from 1933 to 1954.[2] She took a full year sabbatical in 1941, focusing her time on research, and she eventually became full professor in 1945.[2] Wulzen was an academic advisor to two students within the Departments of Zoology and Chemistry: Mary Lorene Wickert (M.S. 1944) and Virginia Lee Wiemar (M.S. 1947).[6]

Scientific Contributions

[edit]

Wulzen is most known for her scientific discovery of the "anti-stiffness factor." This is a fat-soluble vitamin which regulates phosphorous metabolism.

Honors

[edit]

Wulzen received an honorary Doctorate of Science from the University of Oregon in 1943.[7]
