RGB was established in 1992 after the German reunification.
The buildings were originally erected as barracks for Prussian soldiers in 1899.
After the Second World War the Red Army used the barracks continuously until their departure from the area in 1990.
The local Beeskow government decided to then give the buildings a new purpose and converted them into the school you see today.

Jean Pierre Barthelemy Rouanet was born in St. Pons de Thamiere, France to a wealthy family.
He was the youngest of eleven children. Because his parents wanted Rouanet to become a priest, they sent him to the university of Toulouse at the age of 14. Rouanet did not want to be a priest and decided to join the army instead. Being a soldier didn't suit him. He deserted from the army and went to Switzerland, where Prussian soldiers took him into custody and brought him to Breslau, Prussia.

In 1769 he became a guard's officer in Potsdam. At the same time he started giving private French lessons to wealthy families which then led to the official French teacher post at the King's school for boys.

In 1781, once his military service had ended, he accepted the position of senator in Beeskow. He quickly became the Treasurer for the city.
During the Napoleonic wars (1806-1813) Rouanet proved himself valuable to the welfare of the town and district. His French background and level of education helped him negotiate lower demands and dictations by the French on the city of Beeskow, thus making life easier for the people during the French occupation of the town. This earned him high praises by the people of Beeskow who first had critized and opposed him.

Rouanet retired in 1819. At the age of 90, he died on October 8th, 1837.
