Who was Evelyn Willoughby Wade, Alfred North Whitehead’s wife?

Evelyn Willoughby Wade was the wife of the English mathematician and philosopher Alfred North Whitehead. They were married in December 1890, one month before Whitehead began writing his Treatise on Universal Algebra.1

Born in France to a family of impoverished Irish landed gentry, Wade was educated in a convent. She was described as a woman with a great sense of drama and an unusual aesthetic sensibility, and she is credited with enriching Whitehead’s life immensely.1
