2016 Carl E. Akeley Award The 11th annual Carl E. Akeley Award was presented to Marcus von der Hofen of Coastal Gunite Construction for his paper, “East End Crossing.” Shotcrete’s ability to efficiently and effectively place concrete mitigated problems that occurred during the construction of these twin 1940 ft (591 m) tunnels. The paper, published in the Spring 2016 issue of Shotcrete magazine, discussed the challenges of this Kentucky project designed to improve access between the Kentucky and Indiana border while preserving the integrity of an historic Olmsted-designed estate. The award was presented by ASA Publications Committee Chair Ted Sofis. ASA established the Carl E. Akeley Award to honor his founding of what Carl E. Akeley Marcus von der Hofen is today referred to as the shotcrete process. This award is presented to the author(s) of the best technical article appearing in Shotcrete magazine in the past 12 months, as determined by the Akeley Award Committee of ASA. Carl E. Akeley invented the cement gun in 1907 and introduced a commercial version of it at the Cement Show in New York in December 1910. For this reason, Akeley is considered the inventor of the shotcrete process.¹ Born in Clarendon, NY, on May 19, 1864, Akeley was a noted naturalist, taxidermist, inventor, photographer, and author. He made many significant contributions to the American Museum of Natural History and many other museums around the United States. He initially invented the cement gun to repair the façade of the Field Columbian Museum and later used it to improve the quality of his taxidermy exhibits at the museum. Akeley made five expeditions to Africa, during which time he procured many animals for museum exhibits. President Theodore Roosevelt accompanied him on one of those expeditions and encouraged him in his development of the cement gun. During his fifth expedition to Africa, he contracted a virus and died on November 17, 1926. References 1.
