1859: While Alexander has taken an interest in astronomy, it would not lead to a respectable profession in his father's eyes - even for a first born son of a wealthy family. The man has certain standards. Alexander's attendance to astronomy club never really got mentioned.

Though the ideal position of DADA professor was taken at the time, the position of astronomy professor was. His experience with actively participating in astronomy studies and having even written a couple of papers in his spare time, he brings his experience forward and is accepted.
