Ohio Columbus Barber (April 20, 1841 – February 4, 1920) was an American businessman, industrialist and philanthropist. He was called "America's Match King" because of his controlling interest in the Diamond Match Company, which had 85 percent of the market in 1881. He founded the city of Barberton, Ohio in 1891 and moved his manufacturing plant there in 1894. It produced 250 million matches per day. He also founded the Akron City Hospital.

Biography
Ohio Columbus Barber (called O.C.) was born the second son of George and Eliza Barber in Middlebury, a small Ohio village later annexed by Akron. His father made matches by hand, which his sons sold door to door. O.C. received a common school education, and at age 15 began working for his father. At age 16, O.C. Barber became the company salesman. At 20, he was a partner in the business, and by 21 the general manager.

The company had difficulties through the American Civil War, and O.C.'s older brother, George H. Barber, who was a soldier, died of dysentery, one of the many war casualties of disease. By 1880 the Barber Company had become the biggest match-producing company in Ohio and one of the largest in the nation. Unregulated competition made it difficult for the Barber Company to keep stable. In 1881, the Barber Company and 11 other match-producing companies merged into the Diamond Match Company, which dominated the match market, holding 85 per cent of the U.S. Market.

Barber was long a leader in his own home town, Akron. He was, for many years, president of the First National Bank of Akron, and when it was consolidated with the Second National Bank under the name of the First-Second National Bank he was unanimously elected to the presidency of the combined institutions.

To expand manufacturing operations, Barber purchased a large area from Norton Township founding the city of Barberton in 1891. He intended it to be a model for industrial and residential development. Barber developed its early stages through The Barberton Land and Improvement Company. Within a few years, the city had expanded with industrial and residential areas, growing at such a rate it was nicknamed "Magic City". It attracted many new immigrants to its industrial jobs.

In 1894 Barber moved his match-making plant from Akron to Barberton, which helped the city's economy. The factory produced 250 million matches each day.

In 1889, Barber founded and organized the American Straw Board Company. He was one of the early manufacturers of rubber products, and organized and managed the Diamond Rubber Company up to the time of its acquirement by the B. F. Goodrich Company. The sewer-pipe and steel-tube industry next engaged his attention, and he became a western pioneer in this line of endeavor. He founded the Stirling Boiler Company which was merged with the Babcock and Wilcox Boiler Manufacturing Company of Barberton and Bayonne, New Jersey, the concern thus becoming the largest manufacturer of steel boilers in the world. For a number of years they constructed four-fifths of the product used by the United States Navy.

One of the biggest achievements of Barber's career, particularly from the humanitarian and economical standpoints, was the establishment, with Frederick Grinnell and others, of the General Fire Extinguisher Company. Barber was the founder and sole owner of the O. C. Barber Concrete Company, whose plant at Barberton was said to be the largest of its kind in the world. It also made art works in concrete. He originated the O. C. Barber Fertilizer Company, of Barber, Virginia. He also undertook the development of large tracts of land in and about the city of Canton, Ohio, in connection with which he has organized and operated a large plant under the name of the O. C. Barber Allied Industries Company. Some of these lands contain valuable coal, lime, and clay properties.

He was the originator and guiding spirit of Barber Subways, at Cleveland. His plans called for the building of an underground system of subways connecting every railroad entering Cleveland, at the Lake Front, thus facilitating the handling of freight, and the establishment of the great warehouse system on the Lake Shore, where he owned large frontages.

In 1905, he began his last project, to create a scientific farm. He gradually purchased more than 3,000 acres (12 km2). In 1909, Barber used his wealth to commission construction of a three-story, 52-room mansion in Barberton; it was completed in 18 months. Over 300 feet (91 m) long, the mansion was designed in the French Renaissance Revival style by the Akron architects Harpster & Bliss. It cost more than $400,000 to construct and had an area of 25,000 square feet (2,300 m2). Among its amenities was an elevator with a glass skylight. On the grounds were gardens and a 40-acre (160,000 m2) park, designed by a Chicago landscape architect firm. The extravagant building was reported by local and national papers; the New York Times called it the "finest mansion between New York and Chicago." Barber and his family moved into the mansion in October 1910. It stood until 1965, when it was demolished.

In addition, Barber had 35 structures built as part of his experimental, scientific Anna Dean Farm, which covered 3,500 acres (14 km2). He named it after his daughter Anna and her husband, Dr. Arthur Dean Bevan. These were also in the French Renaissance Revival style, as he believed farm buildings should be both beautiful and functional. He intended to have a farm that operated as efficiently as industry. For education, he opened the grounds to the public weekly on Sundays. Many of his facilities were the largest in the world at the time, such as the greenhouses, covering 12 acres (49,000 m2) and heated by the Heating House; Barn #3, 751 feet (229 m) long, 40 feet (12 m) wide and three stories high, the largest barn in the world when constructed in 1912,[4] and the Brooder Barn's incubator. He raised 50,000 chickens, which were allowed "free range". Barber had a barn for 140 thoroughbred Belgian draft horses, used for show and for farm work.

In 1920, Barber died at his mansion in Barberton. He willed his farm to Case Western University, intending it to serve as the basis of an agricultural college, but he failed to complete the financing before his death. Since neither his widow nor the university were able to operate the farm, the university sold most of the property. It was divided and redeveloped.

Family
After the American Civil War, when Barber was 26, he married Laura Brown of Coventry, Ohio. They had one daughter Anna, the namesake years later for a lake and park in Barberton, and a son Charles, who died young. Anna Dean Farm was named after their daughter and her husband, Dr. Arthur Dean Bevan. Laura died in 1894. After being a widower for 20 years, in 1915 Barber married Mary Orr, who had worked as his secretary and shared his vision.
