However, Doetsch never came to the mathematics department and did not hold his lectures in the building where all other mathematicians taught (instead, he used classrooms in the university's main building, normally used by philologists).
Gayunpaman, hindi Doetsch nagmula sa matematika departamento at hindi hold ang kanyang mga lektura sa gusali na kung saan ang lahat ng iba pang mga mathematicians tinuturuan (sa halip, siya na ginagamit classrooms sa unibersidad ng pangunahing gusali, na karaniwang ginagamit ng philologists).
