Architects Harry I. Schenck and Harry J. Williams designed it, and it was built between 1917 and 1918 for the Engineers Club of Dayton.","why_significant":"The building reflects the importance of professional engineering in the Dayton region in the early twentieth century (Criterion A). It is also closely associated with Edward A. Deeds and Charles F. Kettering (Criterion B), nationally significant engineers and inventors who financed it and founded the club. Its principal period of significance runs from its 1918 construction to 1929, when Deeds and Kettering transferred ownership to the club's board of governors.","narrative":"Downtown Dayton's Engineers Club is a brick clubhouse on Monument Avenue, overlooking the Great Miami River near its meeting with the Mad River. Architects Harry I. Schenck and Harry J. Williams, both club members, gave it a restrained Georgian exterior with Bedford limestone trim and a richly paneled Tudor-style interior. Rooms were planned for science and socializing, including a 450-seat auditorium with laboratory utilities on its stage, a library, a dining room and a lobby with a clock that synchronized others through pneumatic tubes. Edward Deeds and Charles Kettering, leading Dayton engineers and inventors, founded the club in 1914 and donated $300,000 in 1916 for the site and building, which opened in February 1918. Dayton was then a center of invention and engineering, and the clubhouse gave local engineers a place to meet, hear lectures and exchange ideas. The building remains in use as a club and keeps most of its original structure, layout and decoration.","period_of_significance":"1918-1929","architect_builder":"Harry I. Schenck and Harry J.
