from the website Explorers of the Millennium:
Jacques Marquette and Louis Jolliet searched together and found the waters of the Mississippi River. They were the first Europeans to follow the course of the river.
Jacques Marquette (also known as Father Marquette) was a Catholic missionary and explorer. He was born in Laon, France. In 1666 came to Québec, Canada and learned Indian languages. From 1669 to 1671 he worked in missions in Sault Sainte Marie (Michigan) and La Pointe (Wisconsin). Around this time, he first met Louis Jolliet, who was trading with Indians in the same area.
Jolliet was a French-Canadian trader and explorer. Jolliet was born near Québec City and raised in a Jesuit seminary. In 1668 he decided that he didn't want to become a priest and he became a trader with the Indians instead. From 1669 to 1671 Jolliet explored a lot of the Great Lakes region. During that time he became a great map maker, also worked as a fur trader, and met Marquette.
In 1672, Jolliet was named leader of an expedition that would explore the northern part of the Mississippi River the following year. Jolliet asked Father Marquette to be the chaplain of this group. Along with five others, Jolliet and Marquette crossed Lake Michigan, and explored the Fox and Wisconsin Rivers, before reaching the Mississippi River. They followed the Mississippi southward past the mouth of the Arkansas River, then returned northward.
After the expedition, Marquette stayed by Lake Michigan and Jolliet returned to Québec. Father Marquette preached among the Illinois Indians until his death in 1675.
