Leaving Dan In My Will

A lawyer meets with the family of a recently deceased millionaire for the reading of the will.
'To my loving wife, Rose, who always stood by me, I leave the house and $2 million,' the attorney reads.
'To my darling daughter, Jessica, who looked after me in sickness and kept the business going, I leave the yacht, the business and $1 million.'

Donald Menzel

Born 11 Apr 1901; died 14 Dec 1976 at age 75. Donald Howard Menzel was an American astronomer who was best known for his arguments against the existence of extraterrestrial UFO's. Menzel was one of the first practitioners of theoretical astrophysics in the United States and pioneered the application of quantum mechanics to astronomical spectroscopy. An authority on the sun's chromosphere, he discovered with J. C. Boyce (1933) that the sun's corona contains oxygen. With W. W. Salisbury he made (1941) the first of the calculations that led to radio contact with the moon in 1946. He supervised the assignment of names to newly discovered lunar features.
