Theodor Georg Knorr (19 October 1859 – 15 April 1911) was an engineer and entrepreneur on the field of railroad technology and founder of the company Knorr-Bremse.

To start the mass production of his brake, Knorr moved the firm to a factory building at Neue Bahnhofsstraße 11/12 (which was later named Alte Fabrik) at Boxhagen-Rummelsburg in autumn 1904.

In 1910, Georg Knorr had to lay down the company's management for health reasons and eventually died during a cure in Davos in 1911.

Only after Knorr's death, from 1913 to 1916, the facades of the factory buildings received their uniform design after plans by Alfred Grenander, by means of altering windows, applying brick dressings and by addition of arcades and sandstone reliefs to the parapets, pillars and dormers.

All that was also undertaken after plans by Grenander and followed the previous line of design – the total area covered by buildings of Knorr-Bremse on both sides of the train tracks now measured 24,380 m².
