Who is your favorite architect? Why

While I believe that every architect has an unique style, these architects and their philosophy's inspire me.
"Every great architect is - necessarily - a great poet. He must be a great original interpreter of his time, his day, his age." ~ Frank Lloyd Wright
"There are 360 degrees. Why stick to one?"~ Zaha Hadid
"Architecture is about the needs of people, the material needs, the things that you can measure." ~ Norman Foster
