The Ludwig-Erhard-Zentrum opened in 2018 in a striking new building on the site of Erhard's birthplace, and it is a serious museum for a seriously underrated figure. Erhard was West Germany's Economics Minister through the 1950s and Chancellor from 1963 to 1966 — the man most responsible for the Wirtschaftswunder, the economic recovery that rebuilt the country from rubble to prosperity in a single generation.
The permanent exhibition covers his life, the theoretical underpinnings of the social market economy, and the broader history of post-war West Germany with real depth. It is well-designed and largely bilingual. Even if you arrive with little interest in economic policy, you will likely leave with more respect for the subject. Allow 90 minutes.
