Franz Miltenberger, born on 14 November 1867 in Buchbrunn and died on 30 May 1959, was chaplain at the Juliansstift in Würzburg after his ordination. From 1891 to 1893 he came to Campo Santo Teutonico as chaplain and Görres scholarship holder. From 1893 to 1894 he continued as chaplain at the college, but at the same time took over, without formal appointment, as director of the RIGG after Stephan Ehses had to return to his home in Trier.

In 1895, however, Ehses returned to Rome again as director. Only now did Ehses become the permanent director.

After his return, Miltenberger worked as a pastor in pastoral care, from 1924 as a cathedral chaplain in Würzburg and under Bishop Matthias Ehrenfried from 1930 to 1948 as vicar general of the diocese of Würzburg.
