Dallas lost an important critical voice on Thursday. David Dillon, architecture critic for the Dallas Morning News for 25 years and a nationally recognized writer on the subject, died of a heart attack at his Amherst, Massachusetts home. Dillon began writing for the Dallas Morning News during the building boom of the early 1980s. He took a buyout from the paper in 2006 but continued to contribute, writing about Cowboys Stadium and the lamentable Sammons Park. His obituary in the DMN includes a wonderful 2006 video interview in which Dillon talks about the role of newspapers, criticism and his career.
