Discovered by May & Baker Ltd and logged in their Test Book on 2 November 1937 under Code No M&B693. Successfully used to treat Winston Churchill's bacterial pneumonia in 1942. In a subsequent radio broadcast he said "This admirable M&B from which I did not suffer any inconvenience, was used at the earliest moment and, after a week's fever, the intruders were repulsed." In 1944 M&B693 also saved Nero, the Royal Circus lion, from pneumonia.[Glasgow Evening News January 1944.]
