Rose Morton

Rose Katherine Morton-Sayre (December 3, 1925 – November 12, 1999)[1] was an American mathematician known for her work in fluid mechanics. The Morton number, a dimensionless parameter used to describe bubbles, is named after her.[2]

Morton was born in Albemarle, North Carolina.[1] She graduated from the University of North Carolina at Greensboro (at that time a women's college) with a bachelor's degree in mathematics in 1948;[1][3] at the university, she was president of the Square Circle Club.[3] She worked at the David Taylor Model Basin, a test facility for the U. S. Navy, from 1949 to 1960.[4]

Her husband was mechanical engineer Clifford L. Sayre, Jr., who also worked at the David Taylor Model Basin from 1956 to 1960.[5]
