Oliver McClintock, aged 82, one of the best-known business men of Pittsburgh, died today in his home at 520 Amberson ave. Death was due to pneumonia contracted last Saturday.
Born in old Allegheny city, Oct. 20, 1839, he was the oldest child of Washington and Eliza Thompson McClintock. His father and grandfather were among the most prominent merchants of what is now the Northside, and early in life Oliver determined upon a business career. After being graduated from local schools, he went to Yale, where he was graduated in 1861. The next year he was admitted to the partnership of W. McClintock & Son. In 1863 he purchased the carpet business of Robinson Bros. and organized the firm of Oliver McClintock & Co. A year later the firm of W. McClintck [sic] & Son was merged into this and the brothers, Walter, Thompson and Frank were each admitted to partnership. In 1897, Thompson McClintock retired and the Oliver McClintock Co. was incorporated.
At the time of the reorganization of the Young Men's Christian association in this city in 1864, Mr. McClintock was elected president. He continued in this position until 1868. His work for municipal reform was the most important period of his life. This work was begun in 1895 with D. D. Bruce and James M. Shields. He was one of the organizers of the old Citizen's league.
In 1866 he was married to Clara Childs, youngest daughter of Harvey Childs. Besides his widow he is survived by three sons, Norman, Walter and Harvey; three daughters, Mrs. Thomas Darling, Mrs. Frank Nichol and Mrs. Wallace Osborn, all of this city.
