Overview
Oglebay Norton Corporation was an American industrial company whose activities centered on the extraction, marketing, processing and transportation of mineral materials. Its roots extended to the mid-nineteenth century, when an iron-ore agency and brokerage business was established to connect mines, shippers and industrial customers. Through successive partnerships and mergers, the business became Oglebay, Norton & Co. in 1890, taking its name from industrialist Earl W. Oglebay and Cleveland banker David Z. Norton. During the late nineteenth and early twentieth centuries, Oglebay Norton developed an important role as a sales and shipping agent for iron-ore properties associated with John D. Rockefeller, including Lake Superior Consolidated Iron Mines and operations on Minnesota's Mesabi Range. The company later built capabilities in Great Lakes transportation. In 1921 it assembled an eleven-vessel fleet that became the Columbia Steamship Company, renamed the Columbia Transportation Company in 1931. The shipping division moved ore and other bulk commodities between Great Lakes ports and industrial facilities, while the wider company managed docks and related logistics infrastructure. Oglebay Norton also pursued the development of lower-grade iron-bearing materials. In 1939 it began studying low-grade minerals and established Reserve Mining Company to develop taconite, a process that supported the eventual commercialization of lower-grade resources. The company later established a taconite mine in Eveleth, Minnesota, during the 1960s. These activities positioned Oglebay Norton across several stages of the minerals supply chain, from resource development and sales agency work to shipping and industrial processing. The company became publicly traded under the Oglebay Norton Company name in 1957. Its Great Lakes transportation history included the SS Edmund Fitzgerald, which was leased and operated through the Columbia Transportation Division. The vessel sank in Lake Superior in 1975; it was owned by Northwestern Mutual Insurance Company rather than Oglebay Norton. In the late 1990s and early 2000s, Oglebay Norton shifted increasingly toward limestone and lime. Under chief executive John Lauer, the company made a series of acquisitions, including Michigan Limestone Operations and Jebco Abrasives, but the expansion materially increased debt. A recession and weak construction market then damaged demand and profitability. The company suspended dividends in 2001, experienced a severe decline in its share price, missed a bond-interest payment in 2004 and filed for Chapter 11 bankruptcy protection that February. It emerged from bankruptcy in January 2005 after restructuring its finances and reducing debt. Following the restructuring, Oglebay Norton sold its remaining freighters in 2006 and concentrated on limestone and lime rather than owning or operating a large Great Lakes fleet. In 2007 it faced a hostile takeover effort from Harbinger Capital Partners. The company adopted an anti-takeover plan while evaluating competing proposals. It ultimately agreed to be acquired by a subsidiary of the Belgian-based Carmeuse Group, a global lime producer. Shareholders approved the merger in November 2007, and antitrust approval was announced in February 2008. Oglebay Norton subsequently ceased to exist as an independent public company and became part of the Carmeuse organization.
History
Oglebay Norton's antecedents lay in the nineteenth-century iron-ore trade. In 1854, H.B. Tuttle & Co. was established as a two-partner iron-ore agency. The business operated as a broker and intermediary rather than simply as a mine owner, linking mineral properties with shippers and industrial buyers. Earl W. Oglebay joined a successor partnership in 1884, and Cleveland banker David Z. Norton joined in 1890. The resulting Oglebay, Norton & Co. became the source of the company's long-term identity. In the 1890s, Oglebay, Norton & Co. served as sales and shipping agent for John D. Rockefeller's Lake Superior Consolidated Iron Mines and managed interests connected with the Mesabi Range in Minnesota. This agency role gave the company experience in coordinating mines, ports, vessels and customers. The business was formally incorporated in 1924. Transportation became a major part of the enterprise. In 1921 the company assembled an eleven-freighter Great Lakes fleet, which became the Columbia Steamship Company and was renamed the Columbia Transportation Company in 1931. During the 1930s, the company also managed four Great Lakes docks. The fleet and dock network supported the movement of iron ore and other bulk materials through the region's industrial supply chain. Oglebay Norton broadened its mineral interests in the late 1930s. In 1939 it began researching the commercial potential of low-grade minerals and established Reserve Mining Company to develop taconite. It later established a taconite mine at Eveleth, Minnesota, during the 1960s. These efforts reflected the industry's search for methods to use lower-grade iron resources as higher-grade ores became less abundant or more expensive. The company adopted the Oglebay Norton Company name and entered public trading in 1957. Its shipping activities later became associated with the SS Edmund Fitzgerald, which was leased through the Columbia Transportation Division. The ship sank in Lake Superior in 1975. Although operated under a lease connected with Oglebay Norton, the vessel was owned by Northwestern Mutual Insurance Company. By the late twentieth century, Oglebay Norton was diversifying beyond its historical iron-ore and shipping base. John Lauer became chief executive in 1998 and pursued acquisitions, including businesses connected with limestone and abrasives. The acquisition program expanded the company's presence in limestone but also increased leverage. In 2000, the company acquired Michigan Limestone Operations and Jebco Abrasives. Michael Lundin, an executive associated with Michigan Limestone Operations, became president in 2001 and later chief executive. The business encountered serious financial difficulty as the economy weakened and construction demand declined. It suspended dividends in 2001, and its share price fell sharply. Debt rose substantially during the period of expansion and subsequent recession. Oglebay Norton missed a bond-interest payment in January 2004 and filed for Chapter 11 bankruptcy protection the following month. Its shares were delisted from Nasdaq during the bankruptcy proceedings. In November 2004, the bankruptcy court approved a reorganization plan, and the company emerged in January 2005 with a reduced debt burden and reorganized finances. After bankruptcy, management narrowed the company's operating focus. In August 2006, it sold its final three freighters to another Great Lakes shipper, effectively ending its direct ownership of a substantial lake-freighter fleet. Oglebay Norton concentrated instead on limestone and lime, businesses viewed as more central to its post-reorganization strategy. The company then became the subject of competing takeover activity. Harbinger Capital Partners launched a hostile offer in July 2007, and Oglebay Norton responded with an anti-takeover plan. By September, the company reported that it had received other proposals. In October 2007, a subsidiary of the Belgian Carmeuse Group agreed to acquire Oglebay Norton. Shareholders approved the merger in November, and antitrust approval was announced on February 8, 2008. The acquisition ended Oglebay Norton's independent corporate existence and brought its remaining operations into the Carmeuse Group.

Industrial minerals
Limestone and lime
Limestone and lime became the company's principal strategic focus in the years before its acquisition.
