PITTOCK, HENRY, L., of Portland, part owner and business manager of the Oregonian, came to Oregon as a young printer looking for work in 1853. He found employment on the Oregonian, then in its third year and was soon foreman and general manager. In 1860 he became owner of the paper, and February 4, 1861, began publishing daily. He has been its manager steadily for forty-three yeas, and his great success and high position are chiefly due to his unceasing care and practical business methods.
