In 1966, the family moved to Cambridge, Massachusetts, where he began kindergarten. Although he was originally given the name Warren Wilhelm Jr at birth by his parents, he was called "Bill" or "Billy" growing up and in his personal life. His father became a heavy drinker which caused emotional distress in the family during this time. His parents divorced when he was seven; he and his brother Donald were raised by Maria and her extended family. Recalling his early childhood, de Blasio said "my mother and father broke up very early on in the time I came along, and I was brought up by my mother's family—that's the bottom line—the de Blasio family. " His father committed suicide while suffering from incurable lung cancer when Bill was 18. De Blasio graduated from Cambridge Rindge and Latin School in 1979, where he served in student government and was affectionately known to peers as "Senator Provolone". [a] When he was 22, he adopted his mother's surname because his father was "largely absent," and he wanted to embrace his Italian heritage. He hyphenated it to Warren de Blasio-Wilhelm in 1983, and formally adopted the name Bill de Blasio in December 2001. He received a Bachelor of Arts from New York University, majoring in metropolitan studies, a program in urban studies, and received a Master of International Affairs from Columbia University's School of International and Public Affairs. He is a 1981 Harry S. Truman Scholar.
