No, not the guilty pleasures list-topping newsreader. No, not the Soho pub either. The 19th Century physician John Snow, obviously. To celebrate his 200th birthday, the London School of Hygiene & Tropical Medicine is hosting an exhibition depicting his famous inquiry into the cholera outbreaks of 1850s London. Not only will you be able to get an insight into his work but this is also a rare chance to go inside the London School of Hygiene & Tropical Medicine itself, which is an architectural delight. Through his medical and street-level knowledge of Soho (he was a local), John Snow worked out that cholera was spread by water and his ahead-of-the-times cartographic research paved the way for future studies of mapping diseases. The exhibition will be open Monday to Saturday from 10am to 5pm until April 17 and it’s absolutely free. But if you can’t wait that long or you want a more experiential look at his work, you can download the mobile map mirroring those on display with the actual locations in Soho. Jude Brosnan
