In Strasbourg, Prof. Dr. Count Solms-Laubach among his botanical teachers. His botanical interests included the genus Chenopodium ; initially Josef Murr supported him by determining forms that were difficult to interpret, later Ludwig came through his own cultural experiments to taxonomic views of Chenopodium that opposed those of Murr.
