Question: Who started the Swiss Reformed Church and initially promoted the Reformation in Switzerland?

full_context: Document 1: Protestantism and Islam: Protestantism is a branch of the monotheistic Christian religion which originated in Europe in the early 16th Century AD/CE. It adheres doctrinally to the doctrine of the Holy Trinity and other theological doctrines of the Catholic Church and the Eastern Orthodox Church, but split from the Western (Roman) Catholic Church as a "Protest" against ecclesiastical corruption, pastoral abuses and certain doctrines of the Roman Catholic Church. Protestantism itself had multiple variations from the start, specifically among followers of Martin Luther, John Calvin, Huldrych Zwingli and later, Thomas Cranmer.
Document 2: Reformed Christian Church in Serbia: Before World War I, the Reformed Christian Church in Serbia (Szerbiai Református Keresztén Egyház in Hungarian) was part of the Reformed Church in Hungary. In the period of the Reformation, Rev Sztáray planted 120 Reformed congregations in the region. In the period of the Ottoman Empire regions of Hungary were part of the Empire and some villages were destroyed. After the Turks were defeated, Hungarian Reformed people came from Debrecen, Szentes. In 1898 a whole Catholic village converted to the Reformed faith, because the Catholic church refused to celebrate the mass in Hungarian language. After World War I this part of Hungary was connected to Serbia. In 1933 the Reformed Church in Yugoslavia was founded. At that time among Hungarians, there were German Reformed comgregations, the Germans arrived in this region in the 18th century. After World War II the Germans were forced to leave the country. There are Czech- speaking and a remnant of German speaking congregations. The church suffered in the Communist regime.

Document 4: Scottish religion in the seventeenth century: Scottish religion in the seventeenth century includes all forms of religious organisation and belief in the Kingdom of Scotland in the seventeenth century. During the sixteenth century, Scotland had undergone a Protestant Reformation that created a predominately Calvinist national kirk, which was strongly Presbyterian in outlook. James VI favoured doctrinal Calvinism, but also episcopacy. His son Charles I authorised a book of canons that made him head of the Church and enforced the use of a new liturgy, seen as an English-style Prayer Book. In the resulting rebellion the Scottish bishops were formally expelled from the Church and representatives of various sections of Scottish society drew up the National Covenant. In the subsequent Bishop's Wars the Scottish Covenanters emerged as virtually independent rulers. Charles I's failure led indirectly to the English civil war (1642–46). The Covenanters intervened on the side of Parliament, who were victorious, but became increasingly alienated from the Parliamentary regime. The Scottish defeats in the subsequent Second and Third civil wars, led to English occupation and incorporation in a Commonwealth of England, Scotland and Ireland led by Oliver Cromwell from 1652 and the imposition of religious toleration for Protestants. The Scottish Covenanters divided into parties of Resolutioners and Protesters.

Seven cantons remained Roman Catholic, though, which led to inter-cantonal wars known as the Wars of Kappel. After the victory of the Catholic cantons in 1531, they proceeded to institute counter-reformatory policies in some regions. The schism and distrust between Catholic and Protestant cantons would define their interior politics and paralyse any common foreign policy until well into the 18th century.
