Pioneer Cotton Seed Oil Mill
Sherman, Grayson County, Texas
Marker Inscription
Here the Sherman Cotton Oil Company was created by John Clement Tassey between 1871-1879, to become, at one time, largest of its kind in the world. Company was at first housed in frame buildings. In 1891 a permanent building was erected; spacious engine room contained white marble slab floor, oak paneled walls, red brick fireplace of English design, and a carved oak staircase. The new facility had a peak capacity of over 400 tons of cotton seed a day. By 1893, was called "largest cotton seed oil mill in the world" in geography textbooks; Texas "Almanac," 1904. Oil from this plant went to ports throughout the world. Tassey was known in Europe as "Mr. Sherman," and Sherman as the city "where the oil comes from." A pioneer in use of cotton seed for edible purposes; in 1902 a preparation of cotton seed oil for cooking was added to company's production. Smaller mills began competing for available seed; by 1903 plant closed because of inability to secure sufficient cotton seed to operate economically. It was reorganized and reopened in 1913 as the Interstate Cotton Oil Refining company. The original permanent building, facing Pecan Street, is now a part of this modern Sherman plant.

The Story
Between 1871 and 1879, John Clement Tassey built the Sherman Cotton Oil Company into what was billed as the largest cotton seed oil mill in the world, its 1891 headquarters boasting a marble-floored engine room and carved oak staircase. Processing over 400 tons of seed a day, the plant shipped oil to ports across the globe and pioneered the use of cotton seed oil for cooking. Seed shortages closed it in 1903, but it reopened in 1913 as the Interstate Cotton Oil Refining Company.
Why it matters
The mill marks a turning point in American food history, when a cotton byproduct once considered waste became a global commodity and a staple of the modern kitchen.
The story behind this marker
AI contextThe era
After the Civil War, cotton was still king across much of the South, and North Texas was a rising part of that kingdom. Farmers planted more and more of it. Every bale of fiber left behind a heavy load of seed, which for a long time was treated as little more than a nuisance. Some went back into the fields as fertilizer or cattle feed, but much of it simply piled up or rotted.
In the decades after the war, inventors and businessmen began to see value in that seed. Pressed, it gave oil. What remained could be made into meal and cake for livestock. A whole industry grew up around a crop's leftovers, and mills appeared across the Cotton Belt.
Sherman, in Grayson County near the Red River, was well placed for it. Surrounded by cotton country and linked by rail to larger markets, it grew into a busy commercial center in the late 1800s.
This was the Gilded Age: large factories, ambitious founders and goods moving around the world by rail and steamship. Few places show it better than a Texas mill whose oil was shipped to ports around the globe.
People & events
The central figure here is John Clement Tassey. Between 1871 and 1879 he built the Sherman Cotton Oil Company. At first it worked out of modest frame buildings. In 1891 the company put up a permanent building, and its engine room was surprisingly elegant for a factory: a white marble floor, oak-paneled walls, a red brick fireplace of English design and a carved oak staircase.
The mill could process more than 400 tons of cottonseed a day at its peak. By 1893 geography textbooks were calling it the largest cottonseed oil mill in the world, and the Texas Almanac repeated the claim in 1904. Its oil went to ports worldwide. Tassey became known in Europe as 'Mr. Sherman', and Sherman as the city 'where the oil comes from.'
The company also looked ahead to the kitchen. In 1902 it added a cottonseed-oil cooking product to its line, part of a pioneering push to use cottonseed for food and not just industry.
Success drew competition. Smaller mills sprang up and bid for the same seed. By 1903 the plant could not get enough to run economically, and it closed. In 1913 it was reorganized and reopened as the Interstate Cotton Oil Refining Company. The original 1891 building, facing Pecan Street, became part of the later plant, and the marker at its base was placed by Anderson, Clayton & Co.'s Foods Division.
Its place in the American story
The story of cottonseed oil is a quiet revolution in American life. A crop's waste became a valuable commodity. That made cotton farming more profitable and fed a new industry across the South. Oil, meal and hulls all found markets, and the seed that once piled up became something to compete for.
It also changed what Americans ate. In the early 20th century, cottonseed oil became a major ingredient in cooking oils and shortenings. It gave home cooks and food manufacturers a cheap alternative to lard and butter. Sherman's move into cooking oil in 1902 put it early in that shift.
The mill's rise and fall is a classic industrial story too. Its size won it world fame. Yet once cheaper local mills competed for raw material, it could not keep running. Access to supply, not just scale, decided who survived.
Finally, it shows how connected even inland Texas was to the world economy. A North Texas mill shipping oil around the globe, with its founder known by his town's name in Europe, is a reminder that the Gilded Age frontier was already part of a global market.
If you visit
The marker stands at an industrial site in Sherman, not a park. The main thing to look for is the surviving 1891 building facing Pecan Street, now part of a larger plant. Look at it with the inscription in mind: somewhere inside once stood a marble-floored engine room with oak paneling and a carved staircase, luxury built to show off an industry's pride.
If the site is still a working facility, admire it from public ground and don't try to enter. The marker and the building's exterior tell the story well enough.
Sherman has more to offer, including a historic downtown that grew during the same boom years the mill represents. It makes a good stop on a trip through North Texas cotton country along the Red River.
As you drive through the area's farmland, keep the mill's lesson in mind. The cotton fields around you once produced something that people across the world cooked with. That turns an ordinary landscape into part of a much bigger story.
