My mother was a high-strung perfectionist. She would check my homework for the slightest imperfection and demand that it be redone if she detected any flaws, which she invariably did. My father, in contrast, was easy going and affable and delighted in helping me with any project.

As an only child lacking siblings and playmates, I was alone a great deal of the time. Much of this was spent reading virtually anything I could get my hands on.
I was born in 1943 and raised in the Bronx, in a high rise apartment complex known as Parkchester, the only child of Max, an accountant who worked in the garment district in Manhattan, and Rose, an elementary school teacher.
My mother's parents, Bernard and Rivka Levine, were from Russia and also immigrated to New York City. My mother, Rose, was the elder of their two daughters. My maternal grandmother's family included several scholars and professionals.
