Also brother of John Green (as mentioned by the user before me) is Hank Green. Together they co-founded their Youtube channel Vlogbrothers, as well as Complexly media, which hosts their other projects such as the educational channels Crashcourse and Scishow. Hank is also an accomplished writer in his own right, having published a two part sci-fi series, The Carls.
