James Buchanan Eads (May 23, 1820 – March 8, 1887) was an American civil engineer and inventor. He held more than 50patents[1] and was known internationally.[2] He designed and built theEads Bridge over theMississippi River inSt. Louis, which was designated aNational Historic Landmark.

Early life and education

[edit]

Eads was born inLawrenceburg, Indiana,[3] and named for his mother's cousin, future President of the United StatesJames Buchanan. Eads' father, Thomas C. Eads, pursued a fortune to no avail and the family moved several times.[4] Eads grew up inSt. Louis, Missouri. The family lost all of their possessions in a steamboat fire as they landed in St. Louis in 1833.[4] Thomas Eads' business ventures in St. Louis failed, and he abandoned his family and moved upriver.[4]

James Eads was largelyself-educated; at the age of 13, he left school to take up work to help support the family. He sold apples on the streets of St. Louis to help support his sisters and mother, who ran a boardinghouse.[4] One of his first jobs was at the Williams & Duhringdry-goods store run by Barrett Williams. Williams allowed the young Eads to spend time in his library, located above the store. In Eads's spare time, he read books onphysical science,mechanics,machinery, and civil engineering. When Eads became successful later in life and Williams suffered hardship, Eads reciprocated Williams' generosity by providing money for Williams' comfort in his old age.[4]

Family

Around 1842, Eads fell in love with Martha Dillon, a woman related to him by marriage. Martha's father was Patrick Dillon, a prominent St. Louis businessman. Patrick did not approve of the couple, as he wanted Martha to marry someone with money and influence. In October 1845, James and Martha wed without her father's consent.[5]

Martha moved in with Eads' parents in LeClaire, Iowa while Eads stayed behind in St. Louis to set up a glass works. Although their living arrangement was supposed to be temporary, the failure of his glass business made it permanent. Eads had many debts to pay off from the failed business and he went back to working in salvage.[5]

Martha died in October 1852 of cholera. She did not live to see Eads become successful. Five years after her death, when Eads retired from working on the river, he had amassed a fortune of $500,000.[5]

Nine years after Martha's death, in 1861, Eads remarried.[5]

Fortune

[edit]

When he was twenty-two, Eads designed a salvage boat and showed the drawings to two shipbuilders, Calvin Case and William Nelson. Although Eads had no previous experience and no capital for the project, Case and Nelson were impressed with him and the three became partners.[4]

At that time, salvaging wrecks from theMississippi River was nearly impossible because of strong currents.[4] Eads made his initial fortune insalvage by creating adiving bell, using a 40 US gal (33 imp gal; 150 L) wine barrel to retrieve goods sunk inriverboat disasters.[4] He also devised special boats for raising the remains of sunken ships from the river bed. Eads did much of the diving himself because the work was so dangerous. His work gave Eads an intimate knowledge of the river, as he explored its depths from the Gulf of Mexico to Iowa.[4] Because of his detailed knowledge of the Mississippi (the equal of any professional river pilot), his exceptional ability at navigating the most treacherous parts of the river system, and his personal fleet of snag-boats and salvage craft, he was afforded the much prizedcourtesy title of "Captain" by the rivermen of the Mississippi and was addressed as Captain Eads throughout his life.[6]

Civil War

[edit]

In 1861, after the outbreak of theAmerican Civil War, Eads was called to Washington at the prompting of his friend, Attorney GeneralEdward Bates, to consult on the defense of the Mississippi River.[7] Soon afterward, he was contracted to construct theCity-class ironclads for theUnited States Navy, and produced seven such ships within five months:[8]St. Louis,Cairo,Carondelet,Cincinnati,Louisville,Mound City, andPittsburgh.[9] He also converted the river steamerNew Era into the ironcladEssex. The river ironclads were a vital element in the highly successful Federal offensive into Tennessee, Kentucky and upper Mississippi (February–June, 1862). Eads corresponded frequently with Navy officers of the Western Flotilla, and used their "combat lessons learned" to improve vessels during post-combat repairs, and incorporate improvements into succeeding generations of gunboats. By the end of the war he would build more than 30 river ironclads.

The last were so hardy that the Navy sent them into service in theGulf of Mexico, where they supported the successful Federal attack on the Confederate port city of Mobile. All senior officers in the Western Theater, including Grant and Sherman, agreed that Eads and his vessels had been vital to early victory in the West. The first four gunboats were built at the Eads' Union Marine Works inCarondelet, Missouri. The next three were built under Eads' contract at the Mound City (Illinois) Marine Railway and Shipyard.[10] Eads' vessels were the first United States ironclads to enter combat. On January 11, 1862 the Eads-built ironcladsSt. Louis andEssex fought the Confederate gunboatsCSS General Polk,CSS Ivy, andCSS Jackson at Lucas Bend, on the Mississippi River. Subsequently, on February 6, 1862, Eads' ironclads capturedFort Henry on theTennessee River.[11] This was over a month before the combat actions of the ironcladsCSS Virginia andUSS Monitor during the March 8–9, 1862Battle of Hampton Roads.

During the war, Eads wrote a check to the War Department for $1,000 to help homeless Confederates and Union sympathizers. After the war, he held a fair to raise money for the thousands of homeless refugees in St. Louis.[4]

Mississippi River bridge

Eads designed and built the first road and rail bridge to cross the Mississippi River atSt. Louis. The Eads Bridge, constructed from 1867 through 1874, was the first bridge of a significant size with steel as its primary material, and it was the longestarch bridge in the world when completed. Eads was the first bridge builder to employ thecantilever method,[citation needed] which allowedsteam boat traffic to continue using the river during construction. The bridge is still in use today, carrying both automobile andlight rail traffic over the river.

Mississippi River designs

[edit]

The Mississippi in the 100-mile-plus stretch between the port ofNew Orleans, Louisiana and theGulf of Mexico frequently suffered from silting up of its outlets, stranding ships or making parts of the river unnavigable for a period of time. Eads solved the problem with a woodenjetty system that narrowed the main outlet of the river, causing the river to speed up and cut its channel deeper, allowing year-round navigation. Eads offered to build the jetties first, and charge the government later.[12] If he was successful, and the jetties caused the river to cut a channel 30 feet deep for 20 years, the government agreed to pay him $8 million. The jetty system was installed in 1876 and the channel was cleared in February 1877.[13] JournalistJoseph Pulitzer, who had known Eads for five years, invested $20,000 in this project.[14] In 1879 the Eads design of jettys at the mouth of the Mississippi River proved to be successful.[15] A flood in 1890 brought calls for a similar system for the entire Mississippi Valley. A jetty system would prevent the floods by deepening the main channel. However, there were concerns about the ability of water moving through a jetty system to cut out the rock and clay on the river bottom.[16] The development of navigable channels at the mouth of the Mississippi River made Eads famous.

In 1982, theAmerican Society of Civil Engineers designated the south pass jetties as aNational Historic Civil Engineering Landmark.[17]

Other work

Eads designed a gigantic railway system intended for construction at theIsthmus of Tehuantepec, which would carry ocean-going ships across the isthmus from theGulf of Mexico to the Pacific Ocean; this attracted some interest but was never constructed.

In 1884 he became the first U.S. citizen awarded theAlbert Medal of the Royal Society of the Arts.

Later life and death

[edit]

Although he came from a humble background, Eads' accomplishments throughout his life earned him wealth and renown. He was so revered that Scientific American proposed that he run for president of the United States.[4]

Eads died while on vacation inNassau, Bahamas, aged 66. Eads and his second wife, Eunice, had moved to New York four years before his death. However, his funeral took place in St. Louis and he was buried inBellefontaine Cemetery inSt. Louis, Missouri in the family vault.[4]

Legacy

[edit]

The towns ofEads, Tennessee;Eads, Colorado; andPort Eads, Louisiana are named for him.

U.S. Route 50 through Lawrenceburg, his hometown, is called Eads Parkway in his honor.

Eads Street is a street running parallel to U.S. Route 1/Richmond Highway in Crystal City, Arlington Virginia.

In 1920, Eads was added to theHall of Fame for Great Americans colonnade, located on the grounds of theBronx Community College in New York.

Eads is memorialized at Washington University in St. Louis by James B. Eads Hall, a 19th-century building long associated with science and technology. Eads Hall was the site ofProfessor Arthur Holly Compton's Nobel Prize–winning experiments in electromagnetic radiation. Today Eads Hall continues to serveWashington University as the site of a number of facilities including the Arts and Sciences Computing Center. Eads Hall was the gift of Captain Eads's daughter Mrs. James Finney How.[18]

Each year theAcademy of Science of St. Louis awards the James B. Eads Award recognizing a distinguished individual for outstanding achievement in science and technology.

Eads is recognized with a star on theSt. Louis Walk of Fame.[19]

In 1927, the deans of America's engineering colleges vote Eads one of the top five engineers of all time, an accolade he shared withLeonardo da Vinci,James Watt,Ferdinand de Lesseps, andThomas A. Edison.[4]

Eads Bridge was designated aNational Historic Landmark by the Department of the Interior in 1964 and on October 21, 1974 was listed as aNational Historic Civil Engineering Landmark by theAmerican Society of Civil Engineers. It was also awarded a Special Award of Recognition by theAmerican Institute of Steel Construction in 1974 on the 100th anniversary of its entry into service. Eads also designed the jetties of the south pass of the Mississippi River, which were designated asNational Historic Civil Engineering Landmarks in 1982.
