Christopher Wren

Sir Christopher Michael Wren /ˈrɛn/PRS (20 October 1632 – 25 February 1723) is one of the most highly acclaimed English architects in history. He was accorded responsibility for rebuilding 52 churches in the City of London after the Great Fire in 1666, including his masterpiece, St. Paul's Cathedral, on Ludgate Hill, completed in 1710.

The principal creative responsibility for a number of the churches is now more commonly attributed to others in his office, especially Nicholas Hawksmoor. Other notable buildings by Wren include the Royal Naval College, Greenwich, and the south front of Hampton Court Palace. The Wren Building, the main building at the College of William and Mary, is attributed to Wren. It is the oldest academic building in continuous use in the United States.

Educated in Latin and Aristotelian physics at the University of Oxford, Wren was a notable anatomist, astronomer, geometer, and mathematician-physicist, as well as an architect. He was a founder of the Royal Society (president 1680–82), and his scientific work was highly regarded by Isaac Newton and Blaise Pascal.

Agatha Christie

Dame Agatha Mary Clarissa Christie, Lady Mallowan, DBE (née Miller; 15 September 1890 – 12 January 1976) was an English crime novelist, short story writer and playwright. She also wrote six romances under the name Mary Westmacott, but she is best known for the 66 detective novels and 14 short story collections that she wrote under her own name, most of which revolve around the investigative work of such characters as Hercule Poirot, Jane Marple, Parker Pyne, Harley Quin/Mr Satterthwaite and Tommy and Tuppence Beresford. She wrote the world's longest-running play, a murder mystery, The Mousetrap. In 1971 she was made a Dame for her contribution to literature.

Christie was born into a wealthy upper-middle-class family in Torquay, Devon. She served in a hospital during the First World War before marrying and starting a family in London. She was initially unsuccessful at getting her work published, but in 1920 The Bodley Head press published her novel The Mysterious Affair at Styles, featuring the character of Hercule Poirot. This launched her literary career.
