William Martin Nygaard
Nygaard was born in Kristiansand as the son of educator and linguist Marius Nygaard (1838–1912) and his wife Elisabeth "Elise" Martin (1842–1923) and brother of Kristen Brunfeldt Nygaard and Finn Nygaard. He married to Constance Wiel, and the couple had seven children, among them Mads Wiel Nygaard and Andreas Melchior Wiel Nygaard, who was the grandfather of William Nygaard. Their daughter Constance Wiel Nygaard married physician Thomas Schram.
He was employed in H. Aschehoug & Co's bookstore in Kristiania in 1887. In 1888, together with Thorstein Lambrechts, he bought the bookstore and the publishing house. Then, in 1900 he became the sole owner of the publishing house and changed the name of the company to H. Aschehoug & Co (W. Nygaard). He was chief executive of the publishing house until 1940 when his son Mads Wiel Nygaard took over as chief executive. William Martin Nygaard continued as chairman of the board.
