Besides acting as city scribe, he was the delegate to the Swiss Diet and to Milan.
During the Council of Basel he sought connections to merchants of Verona, and later entered business relations with Milan in the interest of his father-in-law.
He is the author of the "Silver Book" (Silbernes Buch), an extensive cartulary which was richly ornamented in 1505.
Egloff is the father of chronist Petermann Etterlin who authored the Chronicle of the Swiss Confederation.
