(CNN) -- Friends and colleagues of Apple founder Steve Jobs sent their condolences Wednesday after his death at the age of 56.





On its homepage, Google carried a small notation, "Steve Jobs, 1955-2011." Clicking on Jobs' name took users to the Apple website and its tribute to Jobs.





U.S. House Leader Eric Cantor, R-Virginia:





"There is not a day that goes by, and often not an hour, that a Steve Jobs invention does not better my family's life. Thank you Steve."





U.S. Rep. John Boehner, R-Ohio:





"Steve Jobs changed the world for the better (with) his innovations & genius. R.I.P."





San Francisco Mayor Edwin Lee:





"Steve Jobs was a giant in the world of technology and established the Bay Area as a global center for innovation. He has inspired and changed the Bay Area and the world forever. Steve Jobs was born in San Francisco and his values were reflected in his generous support for results-driven education reform, 21st century philanthropy and bridging the digital divide for our diverse communities. Our thoughts and prayers are with his wife Laurene, his family and friends."





New York City Mayor Michael Bloomberg:





"Tonight, America lost a genius who will be remembered with Edison and Einstein, and whose ideas will shape the world for generations to come. Again and again over the last four decades, Steve Jobs saw the future and brought it to life long before most people could even see the horizon. And Steve's passionate belief in the power of technology to transform the way we live brought us more than smart phones and iPads: it brought knowledge and power that is reshaping the face of civilization. In New York City's government, everyone from street construction inspectors to NYPD detectives have harnessed Apple's products to do their jobs more efficiently and intuitively. Tonight our city -- a city that has always had such respect and admiration for creative genius -- joins with people around the planet in remembering a great man and keeping Laurene and the rest of the Jobs family in our thoughts and prayers."





California Attorney General Kamala Harris:





"California has lost a great leader with the passing of Steve Jobs. His character, intelligence, and creativity changed how the world works and how the world imagines itself.

"Steve Jobs was an extraordinary visionary, our very dear friend and the guiding light of the Pixar family. He saw the potential of what Pixar could be before the rest of us, and beyond what anyone ever imagined. Steve took a chance on us and believed in our crazy dream of making computer animated films; the one thing he always said was to simply 'make it great.' He is why Pixar turned out the way we did and his strength, integrity and love of life has made us all better people. He will forever be a part of Pixar's DNA. Our hearts go out to his wife Laurene and their children during this incredibly difficult time."
