Prestressed concrete is a relatively young form of construction in the United States. The development of the various types of prestressing materials, including anchorages was critical to the success of prestressed concrete as we know it today. This paper reviews the history of prestressed concrete with a focus on post-tensioning related patents in both the United States and abroad. Early patents from 1945 and onward are included up through the present day. The 1950's and 1960's are a primary focus as the decades where prestressed concrete was taking a foothold in the United States.
