Peter Minkowski’s 1977 paper in which he introduced the seesaw mechanism as an explanation of the smallness of the observed neutrino masses has reached 5000 citations in the inspirehep database. This is the most cited theoretical physics paper ever written in Bern, which is even more remarkable since it was not cited for 27 years until Peter protested at a conference in 2004 which incorrectly celebrated the 25th anniversary of the discovery of the mechanism.
