In 1891, the firm was incorporated under the name of Sheldon & Company, with Isaac E. Sheldon as President and Joseph K. Butler as Secretary and Treasurer. The following year they purchased the business of Taintor Brothers. Later the house of E. H. Butler & Company was merged with Sheldon & Company, there being included in E. H. Butler & Company the firm of Cowperthwait & Company of Philadelphia, and a Pittsburgh firm, the name of which I think was H. I. Gurley & Company. Isaac E. Sheldon died about the first of July, 1898, and E. H. Butler was made President, the firm becoming Butler, Sheldon & Company. On January 1, 1903, the business of Butler, Sheldon & Company was purchased by the American Book Company and its books added to the list of that concern. RAND McNALLY & COMPANY.--In 1859 Mr. William H. Rand was operating a job printing business at 148 Lake Street, Chicago. About that time his plant was consolidated with the job department of the Chicago _Tribune_. In 1862, Mr. Andrew McNally, who had been in partnership with Mr. John Collins in the printing and stationery business on North Clark Street, sold his interest and purchased a partnership in the _Tribune_ job office. He became superintendent of the business. In 1864, Rand and McNally bought out the _Tribune_ interest in the job printing, and founded the copartnership of Rand McNally & Company. The Company was incorporated in 1873. The present President of the concern is Mr. H. B. Clow. Rand McNally & Company has been known as map makers, book publishers, atlas makers, bank publishers, ticket manufacturers, creators of map systems, and other specialties. It has published the Dodge Geographies, the Mace Histories, and a number of other large selling educational books. HENRY HOLT & COMPANY.--In 1866, the copartnership of Frederick Leypoldt and Henry Holt was formed under the style of Leypoldt & Holt. From the start they were merely publisher and not retailers or printers. In 1871, H. O. Williams was admitted to the firm; Mr. Leypoldt soon withdrew, and the firm name was changed to Holt & Williams. Two years later Mr. Williams retired and the business was continued as Henry Holt & Company. Charles Holt, a brother of Henry Holt, was an active partner from 1878 to 1903, when the house became a stock company with Henry Holt as President, Roland Holt, Vice President, Edward N. Bristol, Secretary, Joseph F. Vogelius, Treasurer. In 1919, Mr. Vogelius resigned after more than fifty years’ connection with the house.
