Abstract

The editors and editorial assistant wish to express a very sincere and deep appreciation to the distinguished past presidents who in this special issue share the experiences they considered most significant during their term as ACN Board of Directors.

History can be told in many ways, but as readers will have the opportunity to enjoy each one of these articles, our former presidents have left in these letters memories, anecdotes, achievements, have contributed photos and will allow readers to know the beautiful history of our Association, told "from the heart".
