American nurse and naval officer responsible for preparing the Navy Nurse Corps for World War II and then overseeing the group, who simultaneously worked for parity of rank and pay for female officers and their male counterparts.

Dauser attended Stanford University from 1907 to 1909 and in 1911 entered the California Hospital School of Nursing, Los Angeles, graduating in 1914. In September 1917 she joined the naval reserve, going on active duty the next month. In July 1918 she entered the regular navy. After duty at Base Hospital No. 3 in Edinburgh during the final months of World War I, she served tours of duty at naval hospitals in Brooklyn, New York, and San Diego, California, and aboard ship. In 1923 she sailed on the Henderson on President Warren G. Harding's Alaskan visit and attended him during his last illness. She later served on Guam; in the Philippines; at San Diego, California; in Puget Sound off Washington state; and on Mare Island and at Long Beach, California.

In 1939 Dauser was named superintendent of the Navy Nurse Corps. Her task in that post was twofold: to organize and administer a greatly expanded Nurse Corps in preparation for and then throughout World War II and to secure for navy nurses equitable rank and privileges. In July 1942 Congress provided for relative rank for nurses (title and uniform but not the commission, pay, or other benefits of regular rank), and she became a lieutenant commander. Pay was made equivalent in December 1942. In December 1943 Dauser was promoted to (relative) captain, equivalent to Florence A. Blanchfield (Blanchfield, Florence A.)'s army colonelcy and the highest naval rank yet attained by a woman.

In February 1944 temporary commissions were authorized for army and navy nurses. Captain Dauser retired as superintendent of nurses in November 1945 and was awarded the Distinguished Service Medal soon thereafter. Under Dauser the Navy Nurse Corps had grown from 600 members to 11,500. She lived afterward in retirement in La Mesa, California.
