Question: Who founded teh branch of Protestantism practiced in the Nydeggkirche?

Context paragraphs:
English Presbyterianism: Presbyterianism in England is practiced by followers of the Reformed tradition within Protestantism who practise the Presbyterian form of church government in England.  Dating in England as a movement from 1588, it is distinct from Continental and Scottish forms of Presbyterianism.  The Unitarian historian Alexander Gordon stated that whereas in Scotland, church government is based on a meeting of delegates, in England the individual congregation is the primary body of government.  This was the practice in Gordon's day, however, most of the sixteenth and seventeenth century English theoreticians of Presbyterianism, such as Thomas Cartwright, John Paget, the Westminster Assembly of Divines and the London Provincial Assembly, envisaged a Presbyterian system composed of congregations, classes and synods.  Historically Presbyterians in England were subsumed into the United Reformed Church in 1972.  In more recent years the Evangelical Presbyterian Church in England and Wales and the International Presbyterian Church have seen modest growth in England.

Calvinism: Calvinism (also called the Reformed tradition, Reformed Christianity, Reformed Protestantism, or the Reformed faith) is a major branch of Protestantism that follows the theological tradition and forms of Christian practice of John Calvin and other Reformation-era theologians.

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.

Nydeggkirche: The Reformed Nydeggkirche (from the Bernese German expression for "Lower corner") is located on the eastern edge of the Old City of Bern, in the Nydegg section.

Declaratio Ferdinandei: The Declaratio Ferdinandei (English: Declaration of Ferdinand ) was a clause in the Peace of Augsburg, signed in 1555 to end conflicts between Catholics and Protestants within the Holy Roman Empire.  The Peace created the principle of "Cuius regio, eius religio" (Latin for ""whose realm, his religion""), which meant that the religion of the ruler decided the religion of the inhabitants.  The "Declaratio Ferdinandei" exempted knights and some of the cities under the jurisdiction of an ecclesiastical prince if they had practiced Lutheranism for some time (Lutheranism was the only branch of Protestantism recognized under the Peace).  The provision was not publicized as part of the treaty, and was kept secret for almost two decades.

Christianity in Madagascar: Christianity in Madagascar is practiced by just under half the population of the island, often in syncretic form with traditional religious practices.  Protestantism was introduced by the first envoys of the London Missionary Society in 1818, who proselytized and taught literacy through a Malagasy language Bible at the public schools they established in the highlands at the request of King Radama I.  The number of converts remained low but gradually grew under repression during the reign of his successor, Queen Ranavalona I, and the more permissive religious policies of her son, Radama II, and his widow, Queen Rasoherina.  The spread of Protestantism among the Merina upper classes by the mid-1800s, including Queen Ranavalona II, coupled with the growing political influence of the British missionaries, led then-Prime Minister Rainilaiarivony to legislate the conversion of the royal court.  This prompted widespread popular conversion to Protestantism throughout the highlands in the late 1800s.
