How it started
History
John H. Ely, a native of Pennsylvania, established an office in Newark in 1885. In 1895 he was joined in partnership by his son, Wilson C. Ely. John retired in the late 1920s and died in 1932. Wilson continued the firm as a sole proprietor until 1958, when he formed the partnership of Ely & Campbell with John A. Campbell, a Scottish-born architect who had been employed by the Elys since 1910. Wilson died the next year, and Campbell continued the firm alone until his retirement circa 1971. He died in 1976.
