I happened to come across a great video series on You Tube featuring Influential Architects by Doug Patt.  Digging this one of Herzog & de Meuron, but others that are of great interest to me are Renzo Piano, Louis Kahn and Rem Koolhaas. 

It seems to be an ongoing series, so if architecture is of interest to you, I would suggest subscribing to get notified of new videos from Mr. Patt.
