Conrad Freyberg was trained at the Berlin Art Academy and then entered the studio of Carl Steffeck.
He soon specialized in the individual equestrian portraits as well as in whole equestrian groups on a smaller scale. He combined portrait-similarity with elegant representation.
From there he went on to depictions of calm moments from the Franco-German War, which were even more figurative. He painted for example Prince Hohenlohe at Clamart before Paris, the arrival of Prince Friedrich Karl of Prussia on the battlefield of Vionville, the surrender of Metz (1877), the flag parade Prince Friedrich Karl (1883) and the parade on the Longchamp in front of Paris.
Among the smaller groups of riders and portraits, the most important are: Prince Karl of Prussia with his retinue in front of Paris (1872), Prince Karl's ride to the par force hunt (1876), group of Garde du Corps officers (1875) and court hunt in Letzlingen (1881) . Together with Eugen Boermel, he created the Prince Albrecht Monument in Berlin-Charlottenburg in 1901.
Conrad Freyberg died in Berlin in 1915 at the age of 73.
