I just have an enormous respect for these young people who come here and do research with us for half a year", Schrüfer says. "Many of them are very talented and the education they have obtained at home is obviously excellent - especially if it comes to theoretical aspects of electrical engineering, the standard is extremely high. It is a pleasure to work with these students learn to speak russian." But Schrüfer does not only include the foreign students in the scientific projects of the TUM, he and his colleagues also care about the students’ needs out of university: Schrüfer is one of the very few professors in the world who is renting a room in a students dormitory - of course not for himself, but for the foreign students. Everything is booked on his name and he personally makes sure that things work. When his schedule allows, Schrüfer also organises leisure time activities for "his foreigners". He takes them by car on day trips around Bavaria or invites them home. "Without the support of my wife it would not be possible to do all that", he says, "but I think if these young people are here for half a year they should see as much of the country as possible". Why is he doing all this - having written an impressive number of scientific books and textbooks Schrüfer would probably be busy enough without these additional tasks. "First of all it is fun to help these nice, cultural young people", he answers, "and apart from that I think we Germans have quite a bit to make up for". Saying this Schrüfer gets very serious. He mentions his father who had to fight in World War II and he says that he is extremly happy to live in times when nobody is forced to fight against other people.
