Disappearing diner

A man and a beautiful woman were having dinner in a fine restaurant. Their waitress, taking another order at a table a few paces away suddenly noticed that the man was slowing sliding down his chair and under the table, but the woman acted unconcerned. The waitress watched as the man slid all the way down his chair and out of sight under the table. Still, the woman dining across from him appeared calm and unruffled, apparently unaware that her dining companion had disappeared.

After the waitress finished taking the order, she came over to the table and said to the woman, "Pardon me, ma'am, but I think your husband just slid under the table." The woman calmly looked up at her and replied firmly, "No he didn't. My husband just walked in the door."

Born 25 Dec 1876; died 9 Jun 1959 at age 82.German organic chemist, who was awarded the 1928 Nobel Prize for Chemistry for research "for the services rendered through his research into the constitution of the sterols and their connection with the vitamins", the first Nobel prize for work in human nutrition. Windaus began his studies in 1901 with the steroid cholesterol since nothing was known about its structure at the time. In 1926, he proved that ultraviolet light (from sunlight or laboratory sources) activates the compound ergosterol and gives vitamin D, which is valuable in preventing the rickets bone disease. He later synthetically prepared vitamin D3, discovered histamine, and contributed to the synthesis of vitamin B.«
