Ruth Doggett Terzaghi

Ruth Doggett Terzaghi (October 14, 1903 – March 3, 1992) was an American geologist and civil engineer (Peck, 1993, p. 91). She held several teaching positions relating to geology and engineering geology (Peck, 1993, p. 91; Ogilvie, 2003, p. 1275)

Early life Terzaghi was born on October 14, 1903, in Chicago, Illinois, daughter of Lewis and Grace Doggett Later, She published the final version in the Journal of Sedimentary Petrology in 1940 concluding that the relationship between lime mud's compressibility and the pressure in which it can withstand is directly proportional (Tergazhi, 1940, p. 89). finding chemical compounds such as silicon dioxide (Tergazhi, n.d, 115). (Karl & Rogers, 2013). They married each other in 1930, in absentia (i.e. when one member of the union is not present) by Cambridge (Karl & Rogers, 2013). Once the arrangements were complete, Terzaghi departed for France to travel with her new husband (Karl & Rogers, 2013). They reunited on June 7, thus embarking on their lifelong partnership in marriage and geological/ engineering research (Karl & Rogers, 2013).

Their academic career began with a worldwide project campaign from 1930 to 1938 (Peck, 1993). On September 5, 1936, Terzaghi gave birth to her first child, a boy whom they named Eric (Peck, 1993). Due to tensions regarding her husband's work and the brewing war in Europe, Terzaghi returned to the U.S. without her husband in 1938, so she could raise her son safely (Karl & Rogers, 2013). Karl was obliged to stay, as a scandal in which a rival geologist attempted to discredit his work left him on damage control (Karl & Rogers, 2013). As well, he was being scouted by the Austrian-German war effort for assistance (Karl & Rogers, 2013).

Following the war, Doggett Terzaghi engaged in many collaborations with her husband, primarily taking on an editorial role, while also engaging in her own independent work (Peck, 1993).

In May 1941, they had their second child whom they named Margaret. (Peck, 1993; Rogers & Karl, 2013).
