[1] His father, Johann Georg Busch (1823–1895) was a carpenter, wood sculptor and altar builder who established a church art workshop in 1863.

He was given a scholarship, by the Grand Duchy of Hesse, that enabled him to study sculpture at the Academy of Fine Arts, Munich.

In 1888, his eldest brother, Jacob, took over the family business, which enabled him to remain in Munich as a free-lance sculptor.

In 1897, he was awarded the Pro Ecclesia et Pontifice; in 1918, the King Ludwig Cross [de]; and, in 1919 the Order of St. Sylvester.

With the help of his wife, Marie, he was also the proprietor of a publishing house; the "Allgemeine Vereinigung für christliche Kunst" (General Association for Christian Art), which was in operation from 1909 until his death.
