Carl Akeley died on November 18, 1926, only three days after the expedition arrived at Kabara, on the slope of the volcano Mount Mikeno. Derscheid undertook and completed many of the expedition's objectives after Akeley's death: completing a topographical survey, attempting the first census of the mountain gorilla population in the area, conducting a general scientific survey and making recommendations for research sites. In 1928, he co-authored with Mary Jobe Akeley the final report and plan for the park's administration to King Albert I of Belgium. She repeatedly refers to the expedition as the Akeley-Derscheid expedition in her book, although the financial backers of the expedition are named in the title. The Parc national Albert was ceremonially opened on October 19, 1930. It was placed under the authority of an Administrative Council with twenty-one members, with the Prince Albert de Ligne as president and Derscheid as secretary. A board was also created for which Jean-Marie Derscheid was named director.
