Bert Hardy (19 May 1913 — 3 July 1995) was a documentary and press photographer known for his work published in the Picture Post magazine between 1941 and 1957.

Bert Hardy rose from humble working class origins in Blackfriars, the eldest of seven children he left school at age 14 to work for a chemist who also processed photos. His first big sale came when he photographed King George V and Queen Mary in a passing carriage, and sold 200 small prints of his best view of the King. Hardy freelanced for The Bicycle magazine, and bought his first small format Leica 35 mm. He signed on with the General Photographic Agency as a photographer, then found his own freelance firm Criterion.

In 1941 Hardy was recruited by the editor Tom Hopkinson of the leading picture publication of the 1930s and 1940s, Picture Post. Hardy was self-taught and used a Leica - unconventional for press photographers at that time - but went on to become the Post's Chief Photographer, after he earned its first photographer credit for his 1 February 1941 photo-essay about Blitz - stressed firefighters.

Hardy served as a war photographer in the Royal Army Photographic Unit from 1942 until 1946: he took part in the D-Day landings in June 1944; covered the liberation of Paris; the allied advance across the Rhine; and was one of the first photographers to enter the liberated Bergen - Belsen concentration camp to record the suffering there. He also saved some Russian slaves from a fire set by German police in the city of Osnabrück, before photographing the aftermath.

Near the end of World War II, Hardy went to Asia, where he became Lord Mountbatten's personal photographer. He later went on the cover the Korean War along with journalist James Cameron for Picture Post, reporting on United Nations atrocities at Pusan in 1950 and on that war's turning point, the Battle of Inchon, for which he won the Missouri Pictures of the Year Award.

Three of Hardy's photos were used in Edward Steichen's famous "Family of Man" exhibition and book, though not his favorite photo - which shows two street urchins off on a lark in Gorbals - it nevertheless has come to represent Hardy's documentary skill. Hardy himself was photographed many times, including in war time; but three very good photo portraits of him are currently in the Photographs Collection of the National Portrait Gallery.

Having written an article for amateur photographers suggesting you didn't need an expensive camera to take good pictures, Hardy staged a carefully posed photograph of two young women sitting on railings above a breezy Blackpool promenade using a Box Brownie.

Just before Picture Post closed, Hardy took 15 photos of Queen Elizabeth II's entrance at the Paris Opera on 8 April 1957, which were assembled as a photo montage by the magazine's technicians. It was one of the most challenging photo montages ever created, because there were a sizeable live crowd, guards, and other dignitaries, in front of his camera. After leaving Picture Post Hardy became one of the most successful advertising photographers until his retirement in 1964 to his farm in Oxted.

His second wife, Sheila, was a photo researcher for Picture Post and still holds the copyright to his private collection of photos; Getty Images holds the copyright to his Picture Post works.

A memorial plaque honouring him is in the Church of Journalists, St. Bride's, Fleet Street, London.

In October 2008, London Borough of Southwark unveiled a Blue Plaque on Bert Hardy's family home at The Priory Webber Street, Blackfriars. The plaque was erected following a popular vote.
