The images were all downloaded from the St. Andrews Mathematics History Archive Schroedinger biography. They are evidently all over 50 years old and probably over 70 years old. But it is possible that some are still copyrighted although it is possible that no now knows who owns or owned the copyright. In any case, I the use of them falls into the no one cares category. If anyone objects to my displaying them, please contact me and I will resolve the issue.
