1. This photo is of Ham the Chimp, the first chimpanzee to be successfully launched into space in 1961. The snapshot was taken after his return. His name is an acronym for the Holloman Aerospace Medical Center, which is the lab that prepared him for such an important mission. However, he was only given the name upon his return since officials did not want the press to have a name to use for public shaming should the mission have failed. Following the trip, Ham called Washington D.C.’s National Zoo home for 17 years. His remains may now be found at the International Space Hall of Fame in New Mexico.
2. In 1967, Sweden changed its laws so that drivers had to start driving on the right-hand side of the road. The law was implemented to accommodate left-handed vehicles, reduce collisions and keep up with the trends of neighboring countries Norway and Finland. The day the law took effect is called Dagen H, or more popularly “Högertrafikomläggningen” (“The right-hand traffic diversion”), and this picture depicts the mass confusion that ensued. While the switch appeared to be successful in the short term, accident rates and insurance claims returned to normal after a couple years—likely after Swedes grew accustomed to driving on the right hand side of the road.
3. This picture of a girl holding a doll in the rubble of her former home is one of the most poignant and disturbing images from World War Two, and one that succinctly articulates the scope of devastation following the 1940 London bombings.
