Mystery Zdrophotos Contest

Great glory and honor to the one who identifies correctly the five gentlemen pictured below, whom I call for the time being Mr. A, B, C, D, and E.

Mr. A

Studious fellow.  See how his book is propped on a board across the wide arms of his chair?  His bookcase and desk are massive also.  Note the gooseneck lamp and the mid-C20 botanical design of the blotter or whatever it is on the desk.  For the benefit of green youth among the readership, we can mention that the papers in that messy stack include "typescript;" you can see it better upside down.  What is that little merry-go-round gadget sticking up from the desktop? Why have men stopped wearing French cuffs and cufflinks?  Don't they realize how terribly attractive is the style?  Whose office is this and where is it?

Mr. B
Also at work.  Also with strange stuff on his desk.

Mr. C

Mr. D

This man is a lot happier; he's done with work.  Is that beer with the three rings on the label Pabst Blue Ribbon?        
Update:  No - it is Ballantine beer.

Mr. E
