In short

  • Max Gottlieb is Martin's stern teacher of bacteriology and immunology in Arrowsmith, the novel by Sinclair Lewis.
  • He demands experimental proof and distrusts doctors who guess or professors who chase fame.
  • His scientific standards guide Martin, but his pride and harshness make him a demanding teacher.

Who Max Gottlieb is

Max Gottlieb is a German-born professor whom Martin meets at medical school in Winnemac. He is exact, cold and unpopular with students and many of his colleagues.

In his laboratory, a claim needs evidence from an experiment that another person can repeat. He gives Martin a view of medicine built on understanding disease rather than relying on habit.

What Max Gottlieb wants

Gottlieb insists that scientific work serve truth rather than fame, charm or professional success. He has little patience for cheerful claims about health and progress that lack careful proof.

His commitment to exactness does not make him gentle or free of faults. He is proud and lonely, and he can be cruel toward people who disappoint him.

Max Gottlieb and the others in the story

Martin finds Gottlieb both frightening and thrilling, because his laboratory makes honesty a practical discipline. The professor's standards become a measure for Martin's later jobs and colleagues.

When Gottlieb moves to a research institute in New York, he does not forget his former student. Martin's research reaches him there, bringing the teacher and his demanding example back into Martin's working life.
