Vienna-born architect who settled in Milan in 1775 and assisted Piermarini on the Palazzo Ducale. He designed the Villa Casati, Muggiò, (1790s), and the Villa Rocca-Saporiti, called La Rotonda, Borgovico, (again 1790s), each of which has an elliptical salon. His greatest work was the Villa-Reale Belgioioso, Milan (1790–6), the elevations of which are derived from Gabriel's frontages to the Place de la Concorde, Paris (1753–75), although the Order used by Pollack was Ionic rather than Corinthian. He also laid out the gardens in a Picturesque English style, which proved influential, and designed several theatres, including the Teatro Sociale, Bergamo (1805—completed by his son, Giuseppe (1779–1857) ).
