WASHINGTON (AP) - The Supreme Court's upcoming ruling on President Barack Obama's health care overhaul law comes after a century of debate over what role the government should play in helping people in the United States afford medical care. A look at the issue through the years:

1912: Former President Theodore Roosevelt champions national health insurance as he unsuccessfully tries to ride his progressive Bull Moose Party back to the White House.

1929: Baylor Hospital in Texas originates group health insurance. Dallas teachers pay 50 cents a month to cover up to 21 days of hospital care per year.

1935: President Franklin D. Roosevelt favors creating national health insurance amid the Great Depression but decides to push for Social Security first.

1942: Roosevelt establishes wage and price controls during World War II. Businesses can't attract workers with higher pay so they compete through added benefits, including health insurance, which grows into a workplace perk.

1945: President Harry Truman calls on Congress to create a national insurance program for those who pay voluntary fees. The American Medical Association denounces the idea as "socialized medicine" and it goes nowhere.

1960: John F. Kennedy makes health care a major campaign issue but as president can't get a plan for the elderly through Congress.

1965: President Lyndon B. Johnson's legendary arm-twisting and a Congress dominated by his fellow Democrats lead to creation of two landmark government health programs: Medicare for the elderly and Medicaid for the poor.

1974: President Richard Nixon wants to require employers to cover their workers and create federal subsidies to help everyone else buy private insurance. The Watergate scandal intervenes.
