Walter Emerson is a doctor. He is frequently recommended by Joan Holloway to receive contraceptives.
In early 1965, Joan visits him to confirm that she can still give birth. Joan visits the doctor to make sure that two previous abortions won't prevent her from starting a family with Greg. The doctor reassures Joan that she won't have any problems, considering she was still able to get pregnant after the abortion. ("The Good News")
