ALEXANDER FLEMING

Alexander Fleming (1881—1955) came from a Scottish family of farmers. He was born in August, 1881, at Lochfield Farm, the youngest of eight chil­dren. He did research work at St. Mary's Hospital under 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 infections and use of antiseptics, Fleming returned to laboratory work. He was interested in antibacterial tissues.

The first fruit of his search was the discovery of the lusoryme. His epochal discovery in 1928, of antibacterial powers of the mould from which peni- cillin is derived, was a great triumph. He found that a liquid mould culture, which he named penicillin, prevented growth of staphylococci. He died on March 11 1955 in London, and was buried in St. Paul's Cathedral. He is known as the "father of antibiotics" and the brilliant medical student.

When he was fourteen Alec left home and went to live in London with his brother. Alec did not want to leave his happy country life, he would have liked to make farming his career. But his mother decided to send him to the Polytechnic School in London. Fleming also, shot, swam, and played water polo for the regi­ment. But he was never sent with the regiment to South Africa.

Fleming had to pass an examination before he could be allowed to enter a school of medicine. He took a few lessons and then sat for the exam. He passed on top, and became one of the most brilliant students the hospital had ever had. "When he is in a good humour, he is likely to give you a good mark", his teachers would say.
