High Quality Content by WIKIPEDIA articles! Theodor Kullak (12 September 1818 1 March 1882) was a German pianist, composer, and teacher. Kullak was born in Krotoschin (Krotoszyn) in the Grand Duchy of Posen. He began his piano studies as a pupil of Albrecht Agthe in Posen (Pozna ). He progressed sufficiently to excite the interest of the artistic Prince Anton Radziwill in his eighth year. This early ability to attract noble patronage was an art he continued to deploy to advantage for many years to come. In 1829 the prince used his influence to secure a Berlin court concert. He appeared with a co-artist called Henriette Sontag. The usually undemonstrative King Frederick William IV was so delighted that he presented young Kullak with thirty Friedrichs d'or. Six weeks in Berlin was a real adventure which was topped off with a concert in Breslau that was received with gratifying applause. The kindly Prince Radziwill then saw to a rounded education for Kullak, sponsoring his school fees in Sulechów (now in Poland).
