My husband has his Ph.D in organic chemistry & is a research scientist. In the scientific community he is addressed as "Doctor", but he prefers not to be in regular society so as not to be confused with an MD & perhaps be called on to perform a lifesaving procedure in an emergency!

Our daughter is a lawyer & I believe her degree is a J.D.

I'm a housewife, basically, so I'm the old-fashioned Mrs.--Suzy
