I dont know personally any of the people in this entry, but I'd love to sometime! They are my favorite and best builders I know of.
Every time I search mocs I like, usually these names come up!!
I like these people because of their original contributions, ability to show their work via books and internet, and just the amazing ability to build and get others interested in the hobby. I remember in music with my instrument there was a quote "use the musical techniques you have to show off the music, dont use the music to show off your technique.". I love the humility in this statement and these builders seem to emulate this spirit.
1) Wayne Hussey...starred in a "blockumentary", started a seattle lego show, Brick Con and made multiple models..seattle needle tower, batcave and has a cool lego room. I like in blockumentary how they have trading of parts at the library...I would love to go to that. Also nice to see kids given a platform to show their creations.
2) Peter Reid...excellent neoclassic space models and space hangars...great models in his book. I had seen the name legooloverman and didn't put his names together til I saw a pic on flickr connecting the 2.
Great lego idea books, gets info from other builders while making her own books
4) Stephen Niehoff
This has to be the coolest tower/space moc ever!
5) Paul Janssen
Okay I'm biased growing up in ohio but this guy creates the stadium, then uses the seats for a heart fundraiser! What a contribution!
He created books that inspire and has amazing techniques. His lego room is so neat too.
8) Amy Hughes
This was one of the earliest large mocs I ever saw...and done when she was grieving a lost cat...which I didn't understand at the time because I hadn't had a kitty pass away yet
9) Alice Finch
I love how this woman got into legos with her kids...what talent! I love her architecture book she wrote...excellent ideas and amazing talent
multiple idea books that I enjoyed reading for inspiration 
11) Megan Rothrock...her books show such a wide range of subjects and corroboration with other builders. I enjoy looking at her ideas! I like how she creates a story going through the book which makes me think of Bill and Mary in the 6000 idea book
I think that the above builders create something that passes on a part of the Lego spirit and make ideas come to life for newer builders. Again, they stay behind the scenes and let their creativity speak for itself! A lot of talent from these people.
