in 1544, and he reached Strasbourg by 1546. He decided to permanently move to Zürich but he first returned to England to receive his inheritance, and he claims to have been twice imprisoned. In Strasbourg again, in early 1547, he married Anne de Tserclaes (or Tscerlas), a Fleming who with her sister had lived in the household of Jacques de Bourgogne, seigneur de Falais. He proceeded by way of Basel to Zürich, where his Zwinglian convictions were confirmed by constant intercourse with Zwingli's successor, Heinrich Bullinger. He also made connections with Martin Bucer, Theodore Bibliander, Simon Grynaeus, and Konrad Pellikan. During this time Hooper published An Answer to my Lord of Wynchesters Booke Intytlyd a Detection of the Devyls Sophistry (1547), A Declaration of Christ and his Office (1547), and A Declaration of the Ten Holy Commandments (1548). Chaplain at the centre of power It was not until May 1549 that Hooper returned to England. There, he became the principal champion of Swiss Calvinism, against the Lutherans as well as the Catholics, and was appointed chaplain to Edward Seymour, 1st Duke of Somerset, the Lord Protector. Hooper had a hand in the formation of the Zwinglian-inspired Dutch and French Stranger churches in Glastonbury and London. Hooper enjoyed at this time a friendship with Jan Łaski, and served as a witness for the prosecution in Bishop Bonner's trial in 1549. Somerset's fall from power endangered Hooper's position, especially as he had taken a prominent part against Gardiner and Bonner, whose restoration to their sees was now anticipated. However, John Dudley, Earl of Warwick (subsequently Duke of Northumberland), who now dominated the council, continued Somerset's Protestant religious policies. Hooper now became Dudley's chaplain. Vestments controversy After a course of Lenten sermons before the king, he was offered the bishopric of Gloucester. This led to the prolonged vestments controversy; in his sermons before the king and elsewhere Hooper had denounced the "Aaronic vestments" and the oath by the saints, prescribed in the new 1550 ordinal; and he refused to be consecrated according to its rites. Thomas Cranmer, Nicholas Ridley, Martin Bucer and others urged him to submit. Confinement to his house by order of the Council proved equally ineffectual, and it was not until he had spent some weeks in the Fleet prison that the "father of nonconformity" consented to conform, and Hooper submitted to consecration with the legal ceremonies (8 March 1551).
