Main (Thompson) Library location: End window -- North wing. André Wechel (c.15-- – 1581) assumed responsibility of the printing press of his father, Chrétien Wechel, after his death in 1554. Wechel primarily printed the works classical and contemporary authors; among his most notable titles are La Paix by Pierre de Ronsard and Dialectique by Pierre de la Ramée. By 1571, twenty books were attributed to him. In the following year, however, Wechel fled Paris in response to the St. Bartholomew's Day Massacre, an organized assassination of Huguenot Protestants throughout Paris, with the help of diplomat and religious figure, Hubert Languet. Before settling in Germany, Wechel spent some time in Meno, where he published two books in 1575; Wechel then printed in Frankfurt until his death in 1581, when his son Jean Wechel continued his printing press. Wéchel's mark in the Vassar Library consists of the initials A.W., overlapping and surmounted by the top of a four-mark. Over the course of his career, Wéchel may have used over a dozen different devices. The more elaborate of these included imagery of two hands bearing a caduceus – the winged serpentine staff of Hermes – flanked by two cornucopias with the mythological horse Pegasus flying above.
