Charlotte was born in Sayre, Oklahoma, on November 29, 1918 to Arthur and Grace Howard Leach. At the age of 8 she moved to Oklahoma City when her father was appointed to Oklahoma State Supreme Court. While attending the University of Oklahoma, she was a member Alpha Phi Sorority and, after graduating from the University of Oklahoma, earned a Master's in Public Health from the University of Michigan.

In 1941, she traveled to New York City where she worked with Long Island teachers to provide health education in the schools, developed a "health camp for kids" and worked with the local chapter of the New York Tuberculosis Association.

In 1948, Charlotte was named a health education consultant with the National Tuberculosis Association where she developed and implemented workshops for teachers, nurses and school administrators. Because these professionals required current information, two week summer sessions were structured to provide uptodate methods for teaching health in the schools.

When her father became ill in 1967, Charlotte returned to Oklahoma City to take care of him. She was employed by the Oklahoma Health Planning Commission for 17 years and retired, but never stopped working. Every other Monday, Charlotte would work at the First Christian Church in the preparation of mobile meals. In addition, she served on the Deaconess Board with the church. One day a week, Charlotte volunteered her expertise to work with the international students in the graduate program at the College of Public Health, OU Health Sciences Center. She was an active member of the Oklahoma Alliance on Aging, serving on its health and finance committees, and consistently worked to impact legislation within Oklahoma to address older adult issues.

She was a member of the Oklahoma Lung Association of Oklahoma and served as Secretary for the Oklahoma Nutrition Task Force. She served as President of the Oklahoma Public Health Association, sat on the governing counsel of the Oklahoma Public Health Association, was President of the Society for Health Education and belonged to the Oklahoma Interagency Task Force for Health Manpower Data.

She was also past president and lifetime member of the 1889er organization. She was on the Board of Directors of the Oklahoma Health and Welfare Association and was a member of the Oklahoma City Hospitality Club, the Altrusa Club and the City Music Association of Oklahoma City. She was also an active member of the Literacy Council of Oklahoma City and volunteered her time as a tutor assisting adults learning to read.

Although admitting to a hobby of gardening, she never really had the time she liked to spend at it. Charlotte was an example of someone who was not really retired, but redirected her efforts and continued to contribute her talents and wisdom to society. Graveside services will be held at Memorial Park Cemetery, on Thursday, March 27, 2008, at 2:00 p.m.
