Born in Moravia, Georg Flegel settled in Vienna by 1580 where he was an assistant to the painter Lucas van Valckenborch I. Later they both moved to Frankfurt drawn by the local prosperity resulting from Frankfurt's biennial fairs that brought to the city rich foreign merchants, luxury goods and art collectors. Frankfurt was then an important art-dealing city. As an assistant Flegel supplied his employer's paintings with still lifes of fruit, flowers, and table utensils. After Lucas van Valckenborch's death in 1597, Flegel took over his workshop. His two sons were his students at different time.
