The son of Erasmus Darwin, Robert Darwin was a noted physician from Shrewsbury, whose own income as a physician, together with astute investment of his inherited wealth, enabled him to fund his son Charles Darwin's place on the Voyage of the Beagle and then gave him the private income needed to support Charles' chosen vocation in natural history that led to the inception of Darwin's theory of evolution.
