(b. 1571, Antwerpen, d. 1633, Antwerpen)
Theodor [Dirck] Galle, Flemish engraver, publisher and print dealer, son of Philip Galle. He was a pupil of his father. In 1596 he was admitted to the Antwerp Guild of St Luke and about the same time established a print-selling business. He travelled to Italy with his brother Cornelis in the same year. Theodor married the daughter of the Antwerp publisher Jan Moretus the elder and after his father's death in 1612 took over the direction of the Galle workshop and publishing house.
Theodor Galle was chiefly active as a publisher and print dealer. However, while in Rome, he engraved, after his own designs, the Imagines ex antiquis marmoribus, numismatibus et gemmis expressae. He also reproduced compositions by others including Hans Bol, Joannes Stradanus and Peter Paul Rubens.
