The story

Berry sisters

Katharine and Alice Berry came to Kansas City from Wisconsin in 1893. They put each other through school; Katharine being the first to get her medical degree while Alice worked as a schoolteacher, and then obtained her dentist degree—both male-only professions during the 19th century. The women were excluded from professional medical groups because of their gender, and their entrepreneurial spirit was discouraged. But the two persevered and, due to their widowed status, they were permitted to control their own finances, which they poured into their medical work with children.

Children's Mercy Hospital was founded in 1897 when Katharine Berry Richardson, a surgeon, and her sister Alice Berry Graham, a dentist, found a crippled, malnourished girl abandoned in the streets of Kansas City, Missouri and treated and cared for her at a rented bed in a hospital. Since no hospital in the city allowed a female physician on the staff, the sisters continued treating patients by renting beds in a small hospital.

The beds soon became known as the "Mercy Bed". The sisters formed the Free Bed Fund Association for Crippled, Deformed, and Ruptured Children and in 1901, changing it to The Children's Mercy Hospital in 1919.

At first, the public ridiculed the sisters' work, especially the Berry sisters' belief of women-only staffers. Some people believed women should work in the home and not be physicians. But as societal norms changed, the ridicule lessened and public opinion allowed the hospital to grow.

The sisters bought a home in 1903 to work as a hospital, sheltering children. The sisters and few staff members asked the community for supplies, volunteers, and monetary support. Dr. Kate (Katharine Richardson) would keep a sign near the street, letting the public know the needs of the hospital, such as new sheets, pillow cases, bath towels and canned food.

In 1915, construction on what would be the first official hospital began at Independence Avenue. The hospital stayed on the avenue until 1970, when it moved to its current location on Hospital Hill.

When Hurricane Katrina first hit New Orleans in August 2005, Children's Mercy (along with other hospitals) sent helicopters to Tulane Medical Center, Ochsner, and CHNOLA in order to help evacuate pediatric patients from the hospital. Along with helicopters, CMH sent two C-130s to aid in large scale evacuation of pediatric patients from New Orleans.

Children's Mercy is a nonprofit organization that partners with community members, raising money to support access to pediatric care and research in the heart of America.
