WILLIAM R. HOSIER—The simple and direct road to a business is illustrated by the experience of William R. Hosier, who was born in Buddtown, New Jersey, April 3, 1856. Educated in Smaller's School, Buddtown, and the public schools of Jacksonville, New Jersey, he went to Columbus, in that State, when twenty-one years of age, and set about to learn the trade of a carpenter under the tutelage of Edward Mount, an expert workman. He finished his apprenticeship with H. B. Hunt, of Trenton, New Jersey, moved to Camden in 1888, and in 1893 started work for himself as a carpenter and contractor. Naturally, he prospered, and in 1917 he took his son into partnership, the firm now being W. R. Hosier & Son. Mr. Hosier is a director in the East Side Building and Loan Association and also in the Highland Building and Loan Association, and is in touch with all matters relating to those progressive organizations. He is a member of the Woodmen of America; a member of the Shepherds of Bethlehem, Lodge No. 15; of the Brotherhood of America; of the Welcome Circle; and of the East End Civic Association, of Camden.
