The Berlin Institute introduces itself

Dear Visitors,
You are cordially welcome to the Berlin part of the Physikalisch-Technische Bundesanstalt! At the initiative of Werner von Siemens, the Physikalisch-Technische Reichsanstalt (Imperial Physical Technical Institute – PTR) was founded in 1887 on the Charlottenburg campus. Hermann von Helmholtz, who was its first president until his death, resided in a villa on the premises.

Several outstanding personalities of physics worked for the PTR (siehe History of the PTR/PTB).

Following World War II, the PTB in Braunschweig was founded at the initiative of Max von Laue. Based on an agreement between the Federal Republic of Germany and the State of Berlin, in 1953, the PTR merged as the "Berlin Institute" with the PTB located in Braunschweig.

The campus in Charlottenburg consists of several extensively restored old buildings, a fact which was taken into special consideration when designing the necessary new buildings. The entire ensemble is designated as an historic site. The oldest building on the Charlottenburg Campus, the Observatory, has been shining in new splendor since the anniversary year of 2012. The Hermann von Helmholtz Building, which has been designated as an individual historic monument, rounds out the premises to the west.

Today, the Berlin Institute is a modern research and service institute for scientific measurement technology, also known as "metrology". It accommodates two of the eight divisions of PTB, with the subjects thermometry, radiometry, medical physics, mathematics and information technology for metrology. Furthermore, the Berlin Institute (IB) in Berlin-Adlershof uses synchrotron radiation of the electron storage rings Metrology Light Source (MLS) and BESSY II.

The institute is not only a vital part of the scientific landscape of Berlin, but it also represents and is the showcase of PTB for politics and publicity in the federal capital.

Our staff members would be pleased to be able to present to you their research, developmental and service tasks for the economy, society and science.
