Wilhelm Liebknecht
Beust settled in Zürich where he learned the trade of a pedagogue with the innovative teacher Meier while studying botany and chemistry at the university. He obtained an appointment at Karl (nephew of the famous Friedrich) Fröbel's school. Until 1850 another of the teachers at the school was Wilhelm Liebknecht, the Marxist founder of the Social Democratic Workers' Party of Germany (1869–1875).
