On 11 April 1935, Goerdeler ordered the end of Haake's boycott and provided a list of "non-Aryan" physicians permitted to operate under the existing laws and those who were excluded. Critics of Goerdeler such as the American political scientist Daniel Goldhagen have asserted that because Goerdeler published a list of "non-Aryan" physicians to be excluded from practicing under public insurance, Goerdeler was an anti-Semite. By contrast, Goerdeler's defenders like the Canadian historian Peter Hoffmann have argued that Goerdeler's insistence on enforcing the laws served to protect those Jewish physicians entitled to practice.
