Samuel Crell-Spinowski (25 March 1660 in Kluczbork – 9 June 1747 in Amsterdam) was an Arian philosopher and theologian, pastor of the church of the Polish Brethren.
It is recorded that Samuel studied in England, but when Christopher Crell Sr. died in 1680 Samuel's elder brother Christopher Crell Jr. appears to have been not in England, but studying medicine in Leiden, and did not return to take up medicine in London till 1683.
Samuel maintained contacts with representatives of the Reformation in England, Germany and the Netherlands, among others with John Locke,[1] Isaac Newton and Anthony Ashley-Cooper, 3rd Earl of Shaftesbury, who was protector also of Paul Crell.
Samuel Crell was the author of over 20 works of philosophy and theology in Latin, printed in Amsterdam, London and Königsberg.
It is recorded in Polish sources that Samuel had two sons, who emigrated to Georgia, America and spread Socinian teaching there.
