Samuel Whitaker Pennypacker (1843–1916) was a grandson of Joseph Whitaker II; he was a judge, historian, and governor of Pennsylvania. As a young man he worked at the firm of Whitaker & Coudon, iron merchants, in Philadelphia, which sold iron from the family ironworks and other furnaces. •
Joseph Coudon (IV) (1858–1940), grandson of George Price Whitaker, was one of the executors of George Price Whitaker's will, and helped to defend the actions of the executors from legal challenges by some of the other members of the family. He had large land holdings in
Cecil County, Maryland, was the president of several banks there, and was a director of the Wheeling Steel Company at his death. •
Alexander Glass (1858–1941) was a son-in-law of Nelson E. Whitaker. After working for both the LaBelle Iron Works in
Steubenville,
Ohio (which his father Andrew Glass had helped found) and Whitaker family steel plants, he started the Wheeling Corrugating Company, with the help of an investment from his father-in-law. It was the first firm in Wheeling to make zinc-coated steel, corrugated for strength, for building, and it was a success. In 1919 Glass' company, the
La Belle Iron Works, the Whitaker-Glessner Company (which bought the
Portsmouth Steel Company), and the Wheeling Steel and Iron Company combined to form the Wheeling Steel Corporation, which Glass later led until his death in 1941. Wheeling Steel merged with Pittsburgh Steel to form
Wheeling-Pittsburgh Steel in 1968. Glass incidentally made Wheeling, West Virginia famous by placing a large red "Wheeling" label on the company's garbage pails, which were widely used. •
Joseph Whitaker Thompson (1861-1946) was a grandson of Joseph Whitaker II through his daughter Gertrude. He was a federal judge at the district and circuit levels. •
Albert C. Whitaker (1867–1951) was a son of Nelson E. Whitaker; he served as president of the Whitaker Iron Company, the Wheeling Corrugating Company, and the Riverside Bridge Company. He mostly retired from business in 1921, but continued to serve on the board of directors of Wheeling Steel until at least 1929. •
Nelson Price Whitaker (1873–1922) was a grandson of George Price Whitaker (through his son Cecil, who predeceased him). He helped manage the family businesses, serving in 1910 as the general manager of the Whitaker-Glessner Company, Wheeling Corrugating Company, and the Portsmouth Steel Company. He was elected to the West Virginia House of Delegates in 1916, and was chairman of the state Highway Commission until shortly before his death. •
Dwight Homans Wagner (1874–1958) married Eliza "Elsie" Whitaker (1874–1931), daughter of Nelson E. Whitaker. Trained as an architect at
Cornell, Wagner was put to work running the family enterprises, serving as an officer in various Whitaker companies and running his own business manufacturing concrete blocks, bridge piers, and other forms. He eventually served as president of Alexander Glass' Wheeling Corrugating Company, by then a subsidiary of the Whitaker-Glessner Company. ==Fifth generation==
