Who authored the Health insurance reform bill that Obama signed into law?

The Health Insurance reform bill that was signed into law today. Who were the authors of that bill? Who were the sponsors?
--------------------
Apparently, the health insurance companies themselves had significant input. "Last summer, executives from those groups visited the White House and pledged to do their part to help pay for the health bill. By signing on to the effort early and agreeing to absorb some of the costs, they were able to help shape its final form. Only time will tell how smart that trade-off was, but a quick look at the bill passed by the House late Sunday shows it was far from their worst-case scenario: ?A government-run health care plan that would compete against private insurers? Never made it out of the Senate. ?Price controls on Medicare's prescription-drug program that would squeeze drug industry profits? Quietly dropped from consideration last fall. ?Cuts in payments to hospitals serving Medicare patients? Trimmed to modest levels and delayed until 2014." http://www.newsobserver.com/2010/03/23/4…
