Alexander Fleming
(1881 1955)
Alexander Fleming came from a Scottish family of farmers. He was born on August 1881, at Lochfield, the youngest of eight children.
He did his research work at St. Marys Hospital under Sir Almroth Wright, pioneer of vaccine therapy, and became interested in bacterial action and antibacterial drugs. After military service, during which he was able to make further studies of the problems of infection and use of antiseptics, Fleming returned to laboratory work. He was interested in antibacterial substances which would be nontoxic to animal tissues.

The first fruit of his search was the discovery of the lysozyme. His epochal discovery in 1928, of the antibacterial powers of the mould from which penicillin is derived was a great triumph.
He found that a liquid mould culture, which he named penicillin, prevented growth of staphylococci.
He died on the 11th of March, 1955 in London, and was buried in St. Pauls Cathedral. He is known as the Father of antibiotics.

Christmas tree lights
In 1917, when Albert Sadacca was 15 years old, there was a terrible fire in New York City, it had been caused by a Christmas tree catching fire, for in those days Christmas trees were still lit by placing candles on the branches.
Now it just so happened that Alberts family, who had come from Spain, had a novelty business selling wicker cages with imitation birds in them that lit up.
Albert suggested to his parents that they begin making electric lights for Christmas trees. They had lots of bulbs on hand, and it would be much safer than using candles.
The Sadaccas thought Albert had a good idea, but only one hundred strings of electric Christmas tree lights sold in the first year.
After Albert thought of painting the bulbs red, green, and other colors instead of using plain glass, business picked up sharply.

As a matter of fact, Albert Sadacca became the head of a multi million dollar company.
