In the history of physics, Heinrich Rohrer occupies the ground between patient observation and the larger claims it makes possible.
Heinrich Rohrer was born in 1933. His recorded nationality is Switzerland.
Twentieth-century science was collaborative, expensive and political: the questions were pursued by teams, and the answers had consequences that reached well past the laboratory.
In physics the decisive move is usually not the theory but the apparatus built to test it.
The Switzerland setting is not incidental. National academies, funding and language decided which findings travelled and which stayed local, in this period as in ours.
The measure that matters is durability. Results that survive re-examination become the floor of a discipline, and it is on that floor that everything afterwards is built.
A number of his statements have been preserved; they appear below.
Death came in 2013, at 80. By then the contribution had passed into the settled body of physics, where it is used without being credited - the surest sign that it was right.
