College of Fellows

The College of Fellows fulfills a variety of salient functions within APT. Overall, the college advises the Board of Directors on issues regarding the advancement of philosophy and practice of preservation technology. Members of the College serve on committees or in other capacities, as needed. 

The College of Fellows honors those APT members who have provided valuable services to the preservation field and to APT. Each year at the APT annual conference the College of Fellows inducts up to six new members.

The College of Fellows Jury, which consists of five members, reviews the nominations and elects those for invitation to the fellowship.  The jury, a committee of the College of Fellows, includes three Fellows selected by the College, one member at Large, and one member of the Board of Directors selected by the APT President with the approval of the Board of Directors.

A special thank you to APT's 2003 College of Fellows member, François LeBlanc, for preparing a tribute to APT and NTC pioneers from Canada’s National Capital Region for the 2017 APT/NTC Joint Conference.

 Welcome to the New 2019 Class of Fellows

Timothy CroweTimothy Crowe is a licensed architect and a licensed structural engineer with Wiss, Janney Elstner, Associates, Inc., in Northbrook Illinois. Crowe received a Bachelor of Science in Architectural Studies and Master of Architecture (Structures Option) from the University of Illinois at Urbana-Champaign. With over 30 years of experience, he has performed hundreds of evaluations of buildings, structures and cladding systems to address material, structural, or system deficiencies. Crowe’s participation in APT began in the early 1990s attending conferences and local events, which led to more frequent involvement in the early 2000s with participation in workshops, writing for the bulletin, and presenting and/or serving as a session chair at annual conferences. Crowe has been a Co-Chairman of the Preservation Engineering Technical Committee (PETC) from 2008 to Present. His work within the PETC has focused challenges with preservation engineering issues and working on outreach initiatives with committee co-chairs and the PETC membership. As Co-chair, Crowe has led and/or co-led workshop efforts for annual conferences in Denver, Quebec City, San Antonio, Buffalo, and Miami. Crowe’s committee work included collaborations with the PETC and conference committees to develop preservation engineering tracks at annual conferences including Kansas City and Ottawa. Crowe also worked with the APT executive board, as well as the PETC at large (as this is a team effort) in the development of the David Fischetti award (now in its second year), that serves to both advance the awareness of APT and recognizes an exceptional peer-reviewed article annually that benefits the practice of preservation engineering. Crowe also worked with the PETC in the development of the Student Design Competition (now in its fourth year) which also serves to be an APT out-reach attempt to students of both preservation engineering and the trades.
