In 1879 Selling was appointed as a curator of the Astronomical Institute. He proved himself as a very good mathematician and published a series of works on number theory and then on insurance mathematics. On behalf of various ministries, he developed models, with which the pension system in Bavaria could be rearranged.

Selling is a constructor of several calculating machines (see calculating machines of Selling). His machines demonstrated exceptional ideas and ingenuity, but were complex and difficult for manufacturing and work, that’s why they didn’t achieve any market success.

Eduard Selling died on 31 January, 1920, in München.
