Truma established

On returning home after WWII, Philipp Kreis opens a language school in Munich. The lack of mains power in the post-war period poses a major problem for evening courses, giving him the idea of going into gas light production. Due to the increasing demand for gas lights, Philipp finds himself producing and selling them in large quantities in a very short space of time.

On 27 October 1949, he registered his trade under the company name Truma. The brand name Truma stands for the name of the then US president Harry S. Truman, who the company’s founder Philipp Kreis very much admired due to the instrumental role he played in restoring Germany to an industrial nation.


First patent

The Truma gas light solves lighting problems when no electricity is available. On 10 November 1950, a patent is granted for the invention of a gas light for all flammable gases. It is the first patent for Philipp Kreis.

The language teachers no longer teach, instead they work as development and assembly personnel for Truma.


Truma heat radiator

The Truma heat radiator is available. A heater that runs on town and bottled gas and delivers 440 thermal units (= 0.5 kW). It is the ideal small heater for many applications – and, thanks to the exhaust gas system, is also suitable for household purposes and vehicles.



Mass production of light fittings

The Model 55 light is mass-produced. It is the first light on the world market to be fitted with a heat-resistant diaphragm valve. A new pear-shaped opal globe with reflector increases light output by 25%.

Truma now has twelve employees.


Truma valve

The Truma valve with diaphragm seal, patented since 1955, is improved to the "quick-acting valve with rotary switch" and is produced in many models with different connections.

The valve can be used universally for compressed air, gas and many liquids. The diamond-shaped operating handle clearly shows the position of the valve.

The 1950s
Economic boom and a new zest for life
open close

The 1950s are a charmed time of unexpected, rapid and sustained economic growth: the economic miracle. The Volkswagen Beetle is seen as a symbol of the period to this day. It began its own unparalleled success story at this time, with the millionth Beetle rolling off the production line in 1955. Particularly after the horror of the Second World War, the boom helped people in Germany find a new sense of self-assurance. Many of them were finally motivated to do something new and become active and creative. The economic boom that started in Germany eventually spread to the rest of Europe.
