One of the most important acquisitions for the museum was Édouard Manet‘s The Execution of Emperor Maximilian. During the First World War, Wichert belonged to the diplomatic service. After the war, he returned to the Mannheim Kunsthalle and put the collection focus on the Expressionists. In 1923, Wichert was appointed as director of the Städelschule in Frankfurt.
