Friedman BookThe Structure of Skyscrapers in America, 1871–1900, Their History and Preservation
By Donald Friedman

In this new book, award-winning author Donald Friedman presents the development of the structure of skyscrapers at the end of the nineteenth century. He provides the historic context for the emergence of this new building type, as well as a thorough explanation of the technical aspects of construction. Preservation problems are discussed extensively.

A 200-page appendix provides data and images for every known building taller than nine stories constructed in the U.S. between 1853 and 1900—a total of 443 individual buildings.

This definitive book is essential for anyone who is interested in early skyscrapers and especially for those professionals who work with them.

Donald Friedman, co-founder of Old Structures Engineering, has 30 years of experience as a structural engineer, working on both the construction of new buildings and the renovation of existing structures. He has taught at the Pratt Institute, the Rensselaer Polytechnic Institute School of Architecture, and the Columbia University Graduate School of Architecture, Planning and Preservation. He has written numerous articles for technical publications and five books on construction, renovation, and engineering.

To be published by the Association for Preservation Technology in winter 2020.


McKee BookIntroduction to Early American Masonry
Harley McKee’s Classic Book on Historic Masonry

In 1973 esteemed preservation architect and educator Harley J. McKee published Introduction to Early American Masonry, which immediately became an indispensable pillar of preservation practice. APT announces the publication of a second edition, which faithfully reproduces the original text and images, supplemented with an expanded index and a new foreword by John G. Waite.
Filled with scores of photographs and McKee's own sketches, along with accounts from primary sources and personal observations, the book is just as useful to preservation practitioners and students today as when it was first issued. It thoroughly covers all aspects of masonry materials and practices, including sources of building stone, quarrying methods, working and finishing stone, brickmaking, brick shapes and sizes, terra cotta, stucco, and plaster. McKee also explains causes of masonry deterioration and describes all types of cements and mortars for building masonry walls and repointing them. This book was the first to document the history and technology of masonry building materials for a preservation audience. It contains a wealth of information still not found elsewhere in a compact and concise format.
Harley J. McKee, an architect who helped to define the field of preservation during its formative years, served as APT's second president. APT is honored to make this essential volume, long out of print, available once again.
