This is one in a series of articles about the history of PR as part of our celebration of PRNEWS' 75th anniversary. The series is part of a partnership with the Museum of Public Relations. This article looks at Ivy Lee, considered the father of PR. Some 100 years ago Lee established foundations for much of what PR pros do to this day. The list includes the press release, crisis communications and branding, which he did for John D. Rockefeller.
