Who is the people in these photographs?

Factual Questions

“Mars 500” is an isolation study currently underway at the Institute of Biomedical Problems in Moscow. The participants have been sealed in a chamber in which they’ll take part in a simulated long-duration space mission to study the psychological and other effects of long-term isolation.

The participants have decorated their chamber with the portraits of several (no doubt famous) people. But I don’t recognize them all. Here are some photos from inside the chamber.

Specifically, look at Photo #2. There are five portraits visible, in which I identify:
Nicolas Sarkozy, President of France
Angela Merkel, Chancellor of Germany
Aleksandr Lukashenko, President of Belarus
Vladimir Putin, Prime Minister of Russia

But who is the man in the suit and blue tie at the upper left?

This man is also visible in Photo #5. Here as well, Putin and Lukashenko have been moved to make way for an array of cosmonauts. But we also see two more people whom I can’t identify. At the top, from left, we have:

Blue Sash Man
(Charles de Gaulle)
Bowtie Man

2

Blue sash man is Peter the Great

3

The first one kinda looks like Russian Prez Medvedev.

4

Lower left Benny Hill, Upper Left Malcom in the Middle?

5

Kinda looks like Yuri Gagarin, back in his heyday, which would kinda make sense.

6

Bowtie man is Otto Von Bismarck:

Medvedev would make sense, in a group of modern day politicos.

Okay, Peter I and Bismarck are clear, and they make sense alongside de Gaulle as famous past leaders of each participating country. (The Mars 500 crew includes Russians, a Frenchman, and a German.)

The match for Medvedev is probable – it looks a lot like him – and makes similar sense alongside Sarkozy and Merkel (as yabob points out).

I think we’ve got it, unless someone can positively identify Blue Tie Man as not being Medvedev.

I’d say Medvedev looks more like it - I wouldn’t have posted had I seen that link first.
