The first plan for the University called for a Professorship of Engineering and Architecture, but no attention was paid to the latter subject until the appointment of W.L.B. Jenney, to the Professorship of Architecture in 1876. Appropriations failed, however, and the chair was discontinued in 1880, not to be revived until 1906, when a Department of Architecture was organized under the charge of Emil Lorch, A.M., Harvard, '03, with the two departments associated under the title of the Department (later Colleges) of Engineering and Architecture. Within recent years special courses have been organized leading to degrees in Architectural Engineering, Chemical Engineering, and Aeronautical Engineering, as well as special groups of courses in such branches as sanitary, transportation, automobile, hydro-mechanical, industrial, and gas engineering and paper manufacturing. A reorganization of the numerous degrees given at one time in the Engineering College has now reduced the degrees to two, B.S. in Engineering and B.S. in Architecture. [Illustration: THE ENGINEERING QUADRANGLE] Originally the work in engineering was centered in what is now the old south wing of University Hall. The first building on the Campus used exclusively for the engineering courses was the first section of the Engineering Laboratories built in 1881-82, as the result of the insistence of Dr. Frieze, then Acting President, that an unexpended appropriation of $2,500 be used immediately. At short intervals further additions were made and in 1900 the building, now known as the Engineering Shops, assumed its present form. In 1895 a further extension of the work in engineering was required, and the adjacent campus residence was remodeled for the purpose. This proved inadequate almost before completion and in 1902 the construction of the present Engineering Building was authorized. Standing across the southeast corner of the Campus and with the diagonal walk carried through it under a picturesque archway, this is one of the University's largest buildings and forms, with its two wings, and the Engineering Shops and the old Heating Plant, a square known as the Engineering Quadrangle. It was completed in 1904, but a further addition was necessitated in 1909, so that it now has a floor space of about 136,000 square feet, and cost with equipment about $400,000. In the basement of the long wing which extends down East University Avenue is the naval experimental tank, 300 feet long and 22 feet wide, in which models of various types of ships are tested by the Department of Marine Engineering. The only other tank of this character in the United States is at the Washington Navy Yard, and the facilities of the University's tank, therefore, were used extensively by the Government during the late war.
