Another Thanksgiving is upon us. As your family gathers to give thanks, you may wonder who we have to thank for giving us this delicious holiday.

There were the Pilgrims, of course, who started things with the first Thanksgiving in 1621. You could argue credit goes to local Native Americans, who taught the Pilgrims farming tips that helped them survive their first harsh Massachusetts winter. Some say President Abraham Lincoln was responsible, because his 1863 proclamation revived the holiday.
