Michael Servetus

Michael Servetus was a 16th-century Spanish doctor, theologian, and scholar known for his significant contributions to medicine and religious thought. He accurately described the pulmonary circulation of blood, challenging existing ideas. Religiously, he promoted Unitarian views, rejecting traditional Christian doctrines like the Trinity. His ideas conflicted with the dominant Catholic and Protestant churches, leading to his arrest and execution in 1553. Servetus's work remains influential in medicine and religious history, exemplifying intellectual courage and the struggle for free thought during a turbulent period.
