  • Julius Richard Petri Gets a Bacteria-Filled Google Doodle

    You can thank Julius Richard Petri for a lot of your high school biology fun. The inventor of the Petri dish is being honored by Google today with an awesome animated doodle.

    Petri was a German microbiologist who is credited with inventing the device that bears his name while working as an assistant to Robert Koch, who is considered to be the father of modern bacteriology.

    From Wikipedia:

    From 1877 to 1879 he was assigned to the Imperial Health Office (German: Kaiserliches Gesundheitsamt) in Berlin, where he became an assistant to Robert Koch. On the advice of Angelina Hesse, the New York-born wife of another assistant, Walther Hesse, the Koch laboratory began to culture bacteria on agar plates. Petri then invented the standard culture dish, or Petri plate, and further developed the technique of agar culture to purify or clone bacterial colonies derived from single cells. This advance made it possible to rigorously identify the bacteria responsible for diseases.

    Of course, Petri dishes are one of the most important tools in microbiology.

    Today’s Doodle features 6 Petri dishes (in the classic Google colors), which are swabbed by hand and eventually fill up with bacteria forming the rough shapes of G-O-O-G-L-E. Hovering over each dish shows you the source of each culture – a stinky sock, a door handle, a keyboard, a dog, soil and plants, and a kitchen sponge

    I think I’ll go wash my hands now.

  • Miriam Makeba Honored with Google Doodle

    Miriam Makeba Honored with Google Doodle

    Today, Google is celebrating South African singer and political activist Miriam Makeba.

    Makeba was born in Johannesburg in 1932. Her professional career began in 1950 as part of the jazz group the Manhattan Brothers. Shortly after that, Makeba joined an all-female group called the Skylarks. In 1956, she scored her first hit “Pata Pata.”

    After visiting the United States, Makeba was denied entry back into South Africa in 1960. For thirty years, Makeba lived in exile. She returned to her home country in 1990, shortly after Nelson Mandela was released from prison.

    In her long career, Makeba won a Grammy award, sang for President John F. Kennedy, and became a “citizen of the world.” In her lifetime, Makeba held nine different passports and honorary citizenship in ten different countries. Throughout her exile, Makeba was a strong anti-apartheid activist.

    Makeba died in 2008 after suffering a heart attack performing her first hit, “Pata Pata.” Today would have been her 81st birthday.

    In today’s Google Doodle, the famed singer serves at the second “g” in the refashioned logo.
