Otto Neurath seems to pretty much be a Polymath, taking up the mantle of being a political economist, sociologist and a philosopher of science. I mainly like the pictures though and I've been a fan of him since a discovery via Tufte a while back. Otto defined rules for infographics and fought hard to try and create a visual language for information. He did work over the years for numerous countries and organisations and published several books.
Otto set up ISOTYPE (International System of Typographic Picture Education) around 1929 in an attempt to explain to people what they needed to know in the simplest way.
There are only two small rooms at the show and I took some snaps here but it's worth popping by if you're in the area.
It's a shame that more designers working today producing infographics don't pay more attention to work of Neurath and Tufte. Then they might understand what it is they are doing so badly.
All the excellent graphics you can see were produced by German graphics whizz Gerd Arntz, who was Isotype's head of design.
