The University Libraries will host "A Celebration of Central Pennsylvania Architecture and the Work of A. William Hajjar" from 3 to 5 p.m. Jan. 13, in The Eberly Family Special Collections Library, 104 Paterno Library. Activities include a display of original plans and drawings of local houses designed by former Penn State faculty member, A. William Hajjar. The Hajjar architectural drawings are a recent donation by his children to the University. In the 1950s and 1960s, Hajjar challenged the conservative look of the State College community with his contemporary-style homes. More than 50 years later, his 40-plus buildings still delight those who appreciate post-war modern design, and their owners are proud to play a part in conserving a significant part of local history.
