4911 Rosenzweig           Discovered 1953 Oct. 16 at the Goethe Link Observatory, Indiana University.
"Pioneers of the Zone", Jack (1919-1994) and Marcelle (b. 1929) Rosenzweig worked to help the Puerto Ordaz region of Venezuela. They built and operated a plant to make ice blocks for delivery to the mines. They manufactured baseball bats and furniture accessories from Belgian wood and opened a real estate company.
