In which city did Alexander Fleming die?

Alexander Fleming died in London.

He died at his London home on 11 March 1955 after suffering a heart attack. Fleming had spent much of his professional life in the city, especially at St Mary’s Hospital in Paddington, where he conducted the work that led to the discovery of penicillin.

The question can cause confusion because Fleming had strong connections with Scotland. He was born at Lochfield farm near Darvel in Ayrshire and grew up in Scotland, but neither Glasgow nor Edinburgh was the site of his death. His Suffolk country home, The Dhoon at Barton Mills, was another important place in his life, but he did not die there.

Fleming’s ashes are buried in St Paul’s Cathedral in London. His former laboratory at St Mary’s Hospital is preserved as the Alexander Fleming Laboratory Museum, linking the city both to his scientific breakthrough and to his final years.
