The Desloge family (/dəˈlʒ/)[1] is one of the oldest French American families in the United States, centered mostly in Missouri and especially at St. Louis.[2] The family rose to wealth through international commerce, sugar refining, oil drilling, fur trading, mineral mining, saw milling, manufacturing, railroads, real estate, and riverboats. The Desloge family are among the "French Aristocrats in the American West", Carl Eckberg's phrase for the prominent French families in Missouri [3][4] whose impact was "characterized as much by family connections, private enterprise and negotiation as by conquest".[5] The family motto is "Deus Honestum Fortis" (God, Honor, Strength).[6]

The family has funded hospitals and donated large tracts of land for public parks and conservation.[7]




The family's progenitor was Firmin René Desloge, a descendant of French nobility[8][9] who emigrated to Missouri in 1823 to join his uncle Jean Ferdinand Rozier who had arrived in Missouri in 1810 with Rozier's business partner John James Audubon.[9][10][11]

The family's businesses in lead and mercantile in Missouri date from around 1824, when Firmin Rene Desloge built his own smelting furnace as an extension of his Potosi, Missouri, mercantile business. They grew to include the Missouri Lead Mining and Smelting Company in 1874 and the Desloge Lead Company in 1876, inclusively one of the largest and oldest lead mining companies in America.[12][13]

The family moved to St. Louis in 1861, at the outset of the American Civil War, after various attacks at Potosi, Bonne Terre and upon the family lead mining works by both Federal and Confederate armies who sought lead for weapons.

Firmin Rene Desloge's son, Firmin V. Desloge, expanded mining operations and expanded management to Bonne Terre, Missouri; a charter was requested and granted to the Missouri Lead and Smelting Company on June 5, 1874. The corporate name was later changed to "The Desloge Lead Company" on February 21, 1876. Three shafts were sunk during 1876 and 1877 and a new mill was built. In 1886, a fire destroyed the concentrating mill plant and damaged the rest of surface plant of the Desloge Lead Company.[14] Rather than rebuild, Desloge sold the firm to the St. Joseph Lead Company. In 1887, the land was cleared and company houses for his staff were constructed at the location which became known as Deslogetown, present day Desloge, Missouri.[12] Desloge then founded a new company, the Desloge Consolidated Lead Company.[15][16]

To serve his mines, Firmin Desloge also built the first railroads to penetrate the disseminated lead field of St. Francois County, Missouri: the Desloge Railway, the Mississippi River and Bonne Terre Railway[17] and then the Valley Railroad. Firmin Desloge II was also involved with the development of the Iron Mountain and Southern Railroad (aka the Iron Mountain Railroad) from St. Louis, Missouri, to Texarkana, Arkansas. The St. Joseph Lead Company built a 13.5-mile narrow gauge railroad from the mines to a junction with the Iron Mountain Railroad at Summit in Washington County.[18] St. Joe paid two-thirds of the construction costs; the Desloge Company the rest.


Around 1916, the Desloge Consolidated Lead Company moved its corporate offices from Desloge, Missouri, to the Rialto Building in downtown St. Louis. While "St. Louis, with its French ancestry, has been noted as a fur capital, more money passed through St. Louis as a result of the lead business in Missouri than did because of the fur business," wrote Doe Run Company CEO Jeffry Zelm.[19] The oldest St. Louis-based lead family is Desloge.[20]

Desloge's new company operated until 1929, when it was sold to the St. Joe Lead Company for $18,000,000 ($262,639,535 today[21]). "With the absorption of the Desloge concern by the St. Joseph Lead Company, one of the oldest mining companies of the district goes out of existence as a company."[22][23][24] The sale made the family worth more than $52 million[25] alongside W. K. Vanderbilt ($52 million) and A. W. Mellon ($50 million), but only half as wealthy as the Astors ($100 million)[26]

In 1922, Firmin's grandson Louis Desloge (from Jules Desloge) founded Watlow — the name alludes to low-watt heaters to replace steam heat — to manufacture electric heating elements for the shoe industry. In 2011, Watlow, still a Desloge family business, employed 2,000 employees in 13 factories in the United States, Mexico, Europe and Asia; had sales offices in 16 countries; and distributed globally.

Firmin Desloge, II son, Joseph Desloge, designed an industry-specialty electric fuse that would "kill the arc" and founded Killark Electric in 1913. Joseph Desloge also owned Minerva Oil, (a confusing misnomer as it was primarily mining zinc and fluorspar); and founded Louisiana Manufacturing Company and Atlas Manufacturing Company; and fluorspar mining in southeastern Illinois. Joseph Desloge’s son Joseph Jr. owned uranium mines near Moab, Utah, which he and his partner sold to General Electric; he also made money in natural gas exploration in Lycoming County, Pennsylvania.[27]

The Desloge family entertained Russian ballerinas and Shakespearean actors, King Hussein of Jordan, the archduke of Austria (giving him brief shelter after he was deposed by the Nazis),[28] and Anne Morrow Lindbergh.[29]

Firmin Desloge, II died in 1929 as one of the wealthiest men in the world.[26]

Louis Fusz married Firmin Desloge’s daughter Josephine, and the Fusz family played several key roles in the ownership and management of the Desloge Consolidated Lead Company. Louis Fusz was president of Regina Flour Mill Co., and of Desloge Consolidated Lead Co. The Fusz name in St. Louis today is automobiles. In 2018, after 65 years, the Lou Fusz Automotive Network consists of 17 car dealerships, with 15 different automotive franchises.

Theodore (Ted) Desloge Jr was a founding partner in and president of Park 'N Fly, established in 1967[30] as the first[31] and today the nation's leading off-airport parking company[32] Ted has also been director of Valley Forge Corp. and Mississippi Valley Bankshares, Inc.; and founder of Janna Medical Systems.


Christopher D. Desloge (born July 23, 1958) is founder and trustee for Madaket Growth — until 2004, Desloge Consolidated Lead Company[33]— a St. Louis-and-New York-based private family investment holding company;[34]

Rick Desloge was a business and media journalist with the St. Louis Business Journal.[35]


Three Desloges — Diane Waring Desloge (daughter of William L. Desloge), Anne Kennett Farrar Desloge (daughter of Joseph Desloge, Sr.) and Katherine Falk Desloge (daughter of Stephen F. Desloge) — have been "Queen of Love and Beauty" at the Veiled Prophet Ball, a debutante ball held in December in St. Louis.

Kennedy connectionEdit

Durie Malcolm, wife of Firmin V Desloge, III, was long rumored to have to have been briefly married to John F. Kennedy in 1947 in Palm Springs, Florida. No documentation of a marriage between the two is on file with the county, which some have attributed to the Kennedy family having it removed from the county records.[36][37][38] The story was corroborated in 1998 by Malcolm's sister-in-law, Mrs. William L. Desloge, who said, "Of course it's true, we were all there at the parties in Palm Beach with them."[39]


The 1932 bequest of Firmin V. Desloge funded the Firmin Desloge Hospital, today known as St. Louis University Hospital;[40] a separate bequest one year later from his wife, Lydia Desloge, built a Desloge Chapel at the hospital.[41] Firmin V. Desloge willed his original 47 acres of his hand-dug pits of the original lead mining operations and the deeply rutted wagon tracks on a property in Washington County. The family then donated this land for a park, today named Firmin Desloge Park, and dedicated it to the mining families in the area.[42]

In 1955, Joseph Desloge donated to the state of Missouri some 2,400 acres of land acquired over 17 years in Reynolds County.[43] The land, which included a shut-in region and more than two miles of river frontage, today composes the bulk of Johnson's Shut-Ins State Park.[44] He continued donating money to improve the park.[45] Desloge also donated land for Sunset Park in north St. Louis County on the Missouri River; and sold to St. Louis County the 2,300-acre Pelican Island in the middle of the Missouri River (for just $91 an acre[46]) as a nature preserve.[47]

In 2000, Loriel Desloge Hogan established several vast New Hampshire lowland and mountain lands as permanent conservation easements.[48][49]

In 2006, Theodore P. Desloge, Jr., great-grandson of Firmin V. Desloge, and his wife donated $5 million for the Mr. and Mrs. Theodore P. Desloge, Jr. Outpatient Center of St. Lukes Hospital in St. Louis.[50]

In 2013, Christopher D. Desloge founded the Foundation for Commercial Philanthropy, a Missouri and Connecticut nonprofit social entrepreneurial holding company intended to serve the poor and homeless by raising funds through various commercial businesses.[51]
