[1] He was Chaplain General of the French prisoners at Mainz during the Franco-Prussian War, and became an intimate friend of Marshal Patrice de Mac-Mahon.

[3] In April 1874, the Bishop of Pittsburgh, Michael Domenec, assigned Strub to St. Mary's Church in Sharpsburg, hoping that the parish could serve as a place to open a school for Catholic men.

[4] Finally, in 1878, Bishop Tuigg gave Strub permission to open a college in Pittsburgh, though he allocated no resources towards its foundation: no building, land, nor money was available.

[6] Bishop Tuigg did not provide the support he had promised, having learned that the interim rector while Power arrived was a German priest, and only forty students constituted the first class.

[6] In order to avoid provoking the bishop further, Strub left for Arkansas, only two weeks after establishing the Pittsburgh Catholic College, hoping to bring the Spiritan influence to that state.

In 1880, Strub wrote Der Leitstern (English: The Guiding Star), a German-language pamphlet that encouraged immigrants to settle in the colony.
