Her Wiki page tells us that Dr Drew "married Henry Wright-Baker in 1928, which resulted in her dismissal by the university [of Manchester] which had a policy of not employing married women.

In other words, she did her world-changing research without the benefit of a salary. (And she never visited Japan.)
