Just last Friday we had Juan Gris, and a week ago the spring equinox doodle, and the week before that Akira Yoshizawa's 101st anniversary (he was an origami grandmaster). So this is Google's fourth doodle inside a fortnight, and it pays tribute to German-American architect Ludwig Mies van der Rohe.
Mies van der Rohe was born 126 years ago today, and is regarded as one of the pioneers of modern twentieth century architecture.
He believed that buildings should be designed in the most basic and pure form, calling his style of architecture "skin and bones", making use of plenty of open space, and large windows. The doodle itself shows a typical example of what we're talking about.
Mies van der Rohe grew famous for his buildings in Germany, and also furniture designs such as some pretty funky looking chairs and tables. He emigrated to the US in 1938, just before war broke out, and he wasn't alone in that respect.
In the States, he worked on quite a number of buildings in Chicago, and other notable constructions such as the Seagram building in New York. It's a 39 storey, 515 foot tall office with large and plentiful amber coloured windows.
He passed away in 1969, aged 83.
