The Self-Educated Engineer Who Helped Tame the Mississippi
The might of the Mississippi River has tested engineers for centuries. Few have approached its challenges more fearlessly than the self-taught James Buchanan Eads, who risked his career and even his life to exploit its potential
Eads, whose family moved frequently until settling in St. Louis, worked as a clerk for a local merchant as a teenager and began his self-education reading from his employer’s library.
By 1842 the 22-year-old Eads had started his own business salvaging ships that had sunk in the river.
He created a diving bell out of an open-ended barrel with an air hose that connected to a boat at the surface; it allowed him to descend to the bottom of the river in order to recover sunken goods that were previously unattainable due to the river’s strong current.
In 1867 Eads joined the St. Louis and Illinois Bridge Company as chief engineer with the task of building a bridge across the Mississippi River. His proposed design was unprecedented in many ways: it was the first to exclusively use steel—not yet a common building material—employ cantilevers, and carry railroad tracks.
Eads faced criticism, particularly from Army Corps of Engineers Chief Andrew Humphreys, a formally trained civil engineer who became a rival of the autodidact. Despite this, Eads’s bridge officially opened in 1874 as the world’s first all-steel construction.

Eads’s next feat took him to New Orleans where, once again, his unconventional ideas were disputed by Humphreys. Downstream of the city, the mouth of the Mississippi frequently silted in and formed sandbars that prevented ships from sailing in and out of the river basin.
Humphreys and the Corps of Engineers proposed to Congress that a canal be built between the river and Gulf of Mexico to bypass the sandbars; Eads advocated for the construction of jetties.
After several years of persuasion, Eads made a deal with Congress: he would build jetties at his own expense, and Congress would pay him only as the channel reached depth milestones, with the ultimate goal being 30 feet.
Eads built two parallel piers far out into the Gulf to extend the east and west banks of South Pass, building up each jetty wall with willow “mattresses”—trunks of willow trees bound together, stacked, and held down with stones and concrete.
The crevices would fill with sand and mud as the river flowed past them, rendering the jetties impermeable.

Eads’s jetties were completed in 1879, with a channel at the targeted depth of 30 feet, eliminating the silt buildup, and permanently opening the mouth of the Mississippi to ships.
The new jetties exponentially increased the flow of commercial traffic through New Orleans. Just a few years after completion of the jetties, Eads died at the age of 66.
Today, the southernmost point in Louisiana, at the tip of the Mississippi River, is known as Port Eads, named after the man who died without knowing he had changed the course of the river’s history.

Hi Katherine Jolliff Dunn,
Thank you for this history which I suspect very few of us, like myself, knew about. It is amazing what unknown, but obviously talented and motivated people have done in this nation of the FREE without Kings have done. And we need to remember the nameless many whom have lost their lives fighting evil nations to bring freedom to the people of these evil nations. Thank the Holy God for giving us these brave unselfish people whom have lost their lives fighting for people they did not even know.
Have a good and blessed day,
