Who was the first lady to write two books from her point of view and gave money earned then charities?

The first lady who wrote two books from her point of view and donated the earnings to charities was Eleanor Roosevelt.

She wrote her autobiography, "This I Remember," in 1949 and a second volume, "On My Own," in 1958. Both books were critical and commercial successes, and Eleanor Roosevelt donated the proceeds to various charities, including the Eleanor Roosevelt Institute, which she founded.

While other first ladies have written memoirs, Eleanor Roosevelt was the first to explicitly state her intention to donate the earnings to charity. This further cemented her reputation as a champion for social justice and philanthropy.
