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."

Died 14 Aug 1958 at age 58 (born 19 Mar 1900). French physicist and physical chemist who became personal assistant to Marie Curie at the Radium Institute, Paris, and the following year married her daughter Irène (who was also an assistant at the institute). Later they collaborated on research, and shared the 1935 Nobel Prize in Chemistry "in recognition of their synthesis of new radioactive elements." For example, they discovered that aluminium atoms exposed to alpha rays transmuted to radioactive phosphorus atoms. By 1939 he was investigating the fission of uranium atoms. After WW II he supervised the first atomic pile in France. He succeeded his wife as head of the Radium Institute upon her death in 1956.
