But the boy's health was fragile, he suffered from scrofula and rickets (the latter accounted for his bow-leggedness) and was kept under close surveillance of a French doctor, Anselm Levis. Colonel Capet, a Napoleon army prisoner-of-war who settled in Russia after 1812, was the boy's first, and best-loved governor. A German pedagogue, Levy, who succeeded Capet, introduced Mikhail to Goethe and Schiller. He didn't stay for long and soon another Frenchman, Gendrot, replaced him, soon joined by Mr. Windson, a respectable English teacher recommended by the Uvarov family. Later Alexander Zinoviev, a teacher of Russian literature, arrived. The intellectual atmosphere in which Lermontov grew up resembled that experienced by Aleksandr Pushkin, though the domination of French had begun to give way to a preference for English, and Lamartine shared popularity with Byron.
