The land which was bought included everything between the Rocky Mountains and the Mississippi River except Texas. The main port for the second longest river system in the world was within this territory. Although few realized it at that time, the purchase included the vast forests of Arkansas and Minnesota, the oilfields of Oklahoma, the cornfields of Iowa, the wheat lands of the Dakotas, the copper, silver, and gold of Colorado and Montana, the rice and sugar of Louisiana. Without doubt, the Louisiana Purchase was one of the greatest events in the history of the United States. In a single action, as planned, a thirdclass nation successfully doubled its size, united its states and population, and became a great power in the world.展开更多

Much has been achieved, but more work is needed to address many of the distinct challenges to conserving the heritage of the 20^(th) century. In 2011, the Getty Conservation Institute (GCI) launched its Conserving Modern Architecture Initiative (CMAI), which seeks to respond to the outstanding current challenges and contribute to advancing practice in this emerging area of conservation. It began with a survey of the field to identify where existing efforts could be best supported and enhanced, or where knowledge gaps could be potentially filled. In response the GCI built a comprehensive program to meet these identified needs and five years later, a number of activities and projects are underway. These include a series of publications, a training program, historical and technical research and two field projects at Louis Kahn’s Salk Biological Institute (1965) and the house of Ray and Charles Eames (1949), both in California. This paper outlines current GCI efforts, reports on initial outcomes and describes forthcoming activities.展开更多
