The second floor of this ordinary-looking, three-story mission is a museum devoted to the life and work of an astute businesswoman, who was also a teacher, opera singer, and social reformer. She amassed more than a million dollars in her lifetime, yet used it to fund her humanitarian work. Eartha M. M. White crossed the color lines during the Jim Crow era to build not only the first black mission in the state of Florida but also the first black heritage museum. Both still thrive. She developed employment training programs, a senior citizen center, a childcare center for working mothers, and more. Her friends ranged from the internationally powerful to the homeless.Parking at the Clara White Mission and MuseumPark across the street from the mission in the volunteer and staff lot.
