2009 marks the 100th Anniversary of the founding of Irwin & Leighton by Alexander Dickson (A.D.) Irwin, Jr. and Archibald Ogilvie (A.O.) Leighton.
On Saturday evening, May 9th, 2009, employees, guests, and distinguished retirees gathered at the Aronimink Golf Club in Newtown Square, Pennsylvania, to celebrate Irwin & Leighton’s 100th year in business.
As a special momento, every employee received a special First Edition of Our First 100 Years, a commemorative book that highlighted a selection of the many pioneering projects Irwin & Leighton is proud to have partnered in since its founding in 1909. Links to PDFs of the various chapters of the book are below. If you would like a copy of Our First 100 Years, please contact us.
