Rembrandt[7] Harmenszoon van Rijn was born on 15 July 1606 in Leiden,[1] in the Dutch Republic, now the Netherlands. He was the ninth child born to Harmen Gerritszoon van Rijn and Neeltgen Willemsdochter van Zuytbrouck.[8] His family was quite well-to-do; his father was a miller and his mother was a baker's daughter. Religion is a central theme in Rembrandt's paintings and the religiously fraught period in which he lived makes his faith a matter of interest. His mother was Roman Catholic, and his father belonged to the Dutch Reformed Church. While his work reveals deep Christian faith, there is no evidence that Rembrandt formally belonged to any church, although he had five of his children christened in Dutch Reformed churches in Amsterdam: four in the Oude Kerk (Old Church) and one, Titus, in the Zuiderkerk (Southern Church).[9]

As a boy he attended Latin school and was enrolled at the University of Leiden, although according to a contemporary he had a greater inclination towards painting; he was soon apprenticed to a Leiden history painter, Jacob van Swanenburgh, with whom he spent three years.[10] After a brief but important apprenticeship of six months with the painter Pieter Lastman in Amsterdam, Rembrandt stayed a few months with Jacob Pynas and then started his own workshop, though Simon van Leeuwen claimed that Joris van Schooten taught Rembrandt in Leiden.[10][11] Rembrandt opened a studio in Leiden in 1624 or 1625, which he shared with friend and colleague Jan Lievens. In 1627, Rembrandt began to accept students, among them Gerrit Dou.[12]

In 1629 Rembrandt was discovered by the statesman Constantijn Huygens, the father of Christiaan Huygens, (the Dutch mathematician and physicist), who procured for Rembrandt important commissions from the court of The Hague. As a result of this connection, Prince Frederik Hendrik continued to purchase paintings from Rembrandt until 1646.[13]

At the end of 1631 Rembrandt moved to Amsterdam, then rapidly expanding as the new business capital of the Netherlands, and began to practice as a professional portraitist for the first time, with great success. He initially stayed with an art dealer, Hendrick van Uylenburgh, and in 1634, married Hendrick's cousin, Saskia van Uylenburgh.[14][15] Saskia came from a good family: her father had been a lawyer and the burgemeester (mayor) of Leeuwarden. When Saskia, as the youngest daughter, became an orphan, she lived with an older sister in Het Bildt. Rembrandt and Saskia were married in the local church of St. Annaparochie without the presence of Rembrandt's relatives.[16] In the same year, Rembrandt became a burgess of Amsterdam and a member of the local guild of painters. He also acquired a number of students, among them Ferdinand Bol and Govert Flinck.[17]

In 1635 Rembrandt and Saskia moved into their own house, renting in fashionable Nieuwe Doelenstraat. In 1639 they moved to a prominent newly built house (now the Rembrandt House Museum) in the upscale 'Breestraat' (eng.: 'Broadway'), today known as Jodenbreestraat (Jodenbreestraat 4,1011 NK Amsterdam-now) in what was becoming the Jewish quarter; then a young upcoming neighborhood. The mortgage to finance the 13,000 guilder purchase would be a primary cause for later financial difficulties.[17] Rembrandt should easily have been able to pay the house off with his large income, but it appears his spending always kept pace with his income, and he may have made some unsuccessful investments.[18] It was there that Rembrandt frequently sought his Jewish neighbors to model for his Old Testament scenes.[19] Although they were by now affluent, the couple suffered several personal setbacks; their son Rumbartus died two months after his birth in 1635 and their daughter Cornelia died at just three weeks of age in 1638. In 1640, they had a second daughter, also named Cornelia, who died after living barely over a month. Only their fourth child, Titus, who was born in 1641, survived into adulthood. Saskia died in 1642 soon after Titus's birth, probably from tuberculosis. Rembrandt's drawings of her on her sick and death bed are among his most moving works.[20]
