Valentine Junker 

Mr. Junker acted as the WTC Investigation team's liaison in New York charged with helping with the identification of relevant visual material, interfacing with copyright holders, receiving and forwarding to NIST photographs and videos to be used for investigative purposes, and obtaining necessary copyright releases.  Mr. Junker was uniquely qualified for this position based on more than 15 years in the information technology field, with emphasis on digital workflow and image capture, storage, and reproduction technologies and extensive experience in the collection of visual material related to the World Trade Center disaster.   As a volunteer, he worked extensively with the Here Is New York exhibition that chronicled the events of September 11th in a number of shows worldwide.  His responsibilities included developing approaches for acquiring photos and videos, developing procedures for handling material, and specifying and setting up the computer systems used to digitize and archive various forms of photos and video.  Through his efforts with Here Is New York, Mr. Junker became associated with the SEAoNY and FEMA World Trade Center Building Performance Study (BPS).  Initially, he acted as the liaison between the Here Is New York exhibition and the BPS team, but ultimately his duties grew until he was the primary person responsible for the BPAT team's efforts to secure photo and videographic imagery and for establishing a database of images.  He was instrumental in obtaining the necessary copyright releases for images published in the BPS team's final report.
