Christopher Wren

Christopher Wren rebuilt 52 churches and St Paul's Cathedral in London after the 1666 Great Fire, completing the cathedral in 1720 after 45 years of construction at a cost of 721,000 pounds (approximately 150 million pounds today). Wren was also a founding member of the Royal Society and a distinguished astronomer, making him one of history's most versatile intellects alongside Leonardo da Vinci.
