Benjamin McLane Spock was an American pediatrician whose book Baby and Child Care, published in 1946, is one of the biggest best-sellers of all time. Its revolutionary message to mothers was that "you know more than you think you do." Spock was the first pediatrician to study psychoanalysis to try to understand children's needs and family dynamics.
"Successful marriage is an art that can only be learned with difficulty. But it gives pride and satisfaction, like any other expertness that is hard won. It will also be an inspiration to the couple's children and friends. I would say that the surest measures of a man's or woman's maturity is the harmony, style, joy, dignity he creates in his marriage, and the pleasure and inspiration he provides for his spouse. An immature person may achieve great success in a career but never in marriage. "
