Viktor Foerster (Förster) (August 26, 1867 Prague - December 9, 1915) was a Czech painter and mosaicist
 
He was the son of the composer Josef Förster and the younger brother of the composer Josef Bohuslav Foerster. He studied at the Prague Academy of Arts. He exhibited studies from travels in Italy and France, published his contributions in Golden Prague with biblical and mystical themes. In his words, he came up with the idea of ​​dealing with mosaics while he was staying in Monte Casino in Italy and was impressed by the beauty of the old monastic decorations of this technique in the surrounding area and the Abruzzo Mountains. He wanted to try to bring this art to us, especially for durability and resistance to the inconvenience of our climate. Before the First World War he founded the first Czech mosaic workshop in Prague. The realization of this workshop is eg a mosaic of the Virgin Mary with Jesus for the facade of the Church of Our Lady of the Snows in Prague, a mosaic of Christ the Good Shepherd for the church in Slaný-Dolín or a monumental mosaic of the Virgin Mary of Sts. is a series of smaller Foerster works in Pelhrimov and its surroundings - mosaic with the head of Christ on Frantisek Bilek's stone stele “And get us away from the evil 1916” in the Pelhřimov Dean's Garden, mosaics for the cemetery gate in Pelhrimov Bartholomew (together with Frantisek Bilek), book illustrations to Vanek's texts, and reliefs of the Way of the Cross on Kremesnik (perhaps in cooperation with Antonin Bilek). He was also given a votive painting of the Assumption of the Virgin Mary, which was to decorate the Czech chapel in the famous pilgrimage site in Lourdes with a large size of 120 square meters.
