Immediately after the incident, a stunned colleague (a doctoral candidate at a university in Germany) tells me:

Three high-ranking professors from a foreign partner university attended her supervisor’s colloquium as guests. Getting to know these emissaries could have a positive impact on the research and career of all doctoral students present. The professor introduces the doctoral candidates he supervises individually. In the case of his male students, he briefly outlines their current doctoral projects in words of praise. Introducing his only female student and the only woman in the room to the male guests, the professor says: “This is Ms. X, she’s wearing a pretty dress today.”
