|Known for||First Nurse to NASA's First Astronauts|
Dolores B. "Dee" O'Hara (born August 9, 1935 in Nampa, Idaho) was the first aerospace nurse to NASA's first astronauts, laying the foundation to the field of Space nursing. O'Hara was the official nurse to the Mercury Seven astronauts and their families, continuing to support the Gemini Program, Apollo astronauts and Skylab. 
O'Hara was born on August 9, 1935 in Nampa, Idaho. In 1956 graduated from the Providence Hospital School of Nursing in Portland, Oregon. After graduation, between 1956 - 1957 O'Hara completed coursework in Operating Room Technique in the University of Oregon. She worked as a surgical nurse at the University of Oregon Medical School. Because of back problems, she moved on to work with three diagnosticians in Portland, Oregon, and learned how to do lab work and X-rays.
U.S. Air Force
Convinced by her roommate, she decided to join the Air Force, which was not common for women to do at the time. O'Hara completed officers' training at Maxwell Air Force Base Alabama at the rank of second lieutenant.
In May 1959, O'Hara was assigned to Patrick Air Force Base in Cape Canaveral, Florida, in support of the Mercury Program. In 1963 she was officially assigned as the Office Nurse in Cocoa Beach, Florida. 
In November 1959, O'Hara became the first Staff Nurse of the Mercury Program. Her job was to set up the Aeromed Lab, the crew sleeping quarters, the exam area for the astronauts in Hangar S, and be with them as their nurse. Colonel George Knauf, Center Commander of Patrick Air Force Base wanted to have a nurse in the Mercury program team because he thought the astronauts would be more likely to share information with the staff nurse than with the flight surgeon who could ground them. Also, the nurse would be around enough to identify when they are not feeling well.
O'Hara gained the confidence of the astronauts. She had made a deal with the astronauts that they would not hide information from her, and she would not betray their confidence, unless, she thought it may jeopardize them or the mission. She was the only nurse assigned to the Astronauts. O'Hara became close to the astronauts and their families. Before every launch she performed the pre-flight physicals including height, weight, temperatures, blood pressure measurements. The astronauts would not agree to let anyone else but O'Hara drew blood before launch.
O'Hara also helped set up the portable hospital at the Grand Bahama Island to support post flight examination and, if needed, treat injured astronauts after landing (especially in the sub orbital flights). Additional Nurse, Lieutenant Shirley Sineath was assigned as a surgical nurse on the recovery team.
In 1964, she moved to Houston to set up the Flight Medicine Clinic at the Johnson Space Center. She was the Occupational Health Nurse until 1967, and the manager of the Preventive Medicine Office between 1967-1971.
During the Gemini Program she worked with the astronauts and the families, while she was the only nurse along the five flight surgeons. O'Hara performed all the pre-flight checks, fly down to Cape Canaveral and stayed there until the crew was recovered and brought back to the Cape, to do the post-flight exams. In Houston she performed all the routine check ups and more detailed exams, along with all of the administrative tasks, and taking care of the astronaut families. In addition to taking care of the astronaut families, the clinic also took care of the NASA aircraft operations pilots and all the crew personnel. O'Hara supported the Apollo Program astronauts, though tragedies (like the Apollo 1 fire) and accomplishments and Moon landings.
Between 1971 and 1974 O'Hara was the manager of the Medical Operations Division in the Flight Medicine Branch until moving to Ames Research Center.. She was involved in the decision to ground astronaut Ken Mattingly from Apollo 13 due to the concern he might have contracted German measles.
O'Hara participated in every launch in the Mercury, Gemini and Apollo programs. After Skylab, she was also invited to participate in the Apollo-Soyuz Test Program (ASTP) and the first shuttle flight in 1983.  During her time as the Astronaut's Nurse, she received a lot of fan mail.
Ames Research Center
In 1974, O'Hara moved to the Ames Research Center where she was the manager of the Human Research Facility. She was in charge of the bed rest studies. During these studies the researchers found parallels between bed rest study and actual in-flight stuff.  She was manager of the Human Research facility until her retirement in 1997.
After her retirement O'Hara continued to volunteer at the Ames Human Research Center. She was also an outside member of the Human Research Institutional Review Board.
