NEW BOOK examines the life and work of architect Paul R. Williams. Cover photo is the Collins House located in Windsor Square. As we celebrate the triumphs and struggles of African American History this month, there is perhaps no local example that highlights such achievements better than the residential designs of architect Paul R. Williams. In his six-decade career, Williams worked on more than 3,000 projects that ranged from modest homes to extravagant mansions commissioned for the city’s elite. Renowned for his mastery of harmonious proportions and signature undulating lines, Williams’ residential designs were simultaneously graceful and relaxed. Williams’ inspiring story is examined in a new book, “Master Architects of Southern California 1920-1940: Paul R. Williams,” published last month by Tailwater Press and Angel City Press. The 212-page book is the fourth in a series co-authored by local real estate agent Bret Parsons along with architect Marc Appleton. Stephen Gee also is a co-author of this volume.
