Heinrich was a colleague of Indiana Jones. By 1957, when Jones was put on leave by Marshall College, Jones considered getting a teaching job in Leipzig, believing that Heinrich could probably help arrange it, and that he owed Jones a big favor. Jones mentioned this to Charles Stanforth while packing up his suitcase.
