Today in History - February 13, 1959 - the first Barbie doll goes on sale. Barbie’s inventor, Ruth Handler, was inspired by seeing that her daughter, Barbie, and her girl friends enjoyed playing with adult female dolls, but most dolls at the time were baby dolls. Handler created 3D models of dolls that she thought would inspire her daughter’s dreams and took them to the ad executives at Mattel, Inc. Although Mattel was founded by Ruth Handler and her husband, Elliot, some years earlier in their garage, the “all male” committee rejected the idea as too expensive and without enough appeal in the market. Determined not to give up on the idea, Ruth Handler continued to further develop her product and went to Europe to gain fashion ideas and market her concept. Mattel soon appreciated the potential impact of this concept and changed their mind, debuting Barbie at the American Toy Fair in New York City in 1959. This new doll concept immediately set new sales records for Mattel ( 351,000 dolls is reported for the first year; sold at $3 each ).

The first permanent photograph was made in 1826 by Joseph Niepce. Together with Louis Daguerre they further refined the process. The process involved silver-coated copper plates mixed with iodine to create a layer of silver iodine. After being exposed to light for several minutes the plate was exposed to mercury vapor and heated to 75 degrees Celsius. Though the prints that these created were not reproducible they were still amazingly popular. These pictures were known as daguerrotypes, and took several minutes of exposure. In fact when taking portraits subjects had to remain still for several minutes. And pictures of scenery often didn’t show people because they moved to fast to be caught by the slow exposure. In 1839 the French Academy of Sciences announced this process.
