Today, Kirk Johnson announced that he will be stepping down as the Sant Director of the Smithsonian’s National Museum of Natural History after 14 years in the role, as he prepares to join the Denver Museum of Nature and Science as its next President and Chief Executive Officer.
An advocate for science, nature and the power of museums to influence the future, Johnson has led the efforts to leverage the museum’s collection of more than 148 million objects and specimens to expand our scientific knowledge of the natural world and its cultures and pique the curiosity of millions of visitors about their planet and their own backyards.
At the museum, Johnson has overseen one of the world’s preeminent centers of natural history research, whose scientists published more than 11,000 peer-reviewed papers and named over 4,000 species during his tenure.
Johnson has also placed great emphasis on ensuring a welcoming and meaningful experience for the museum’s 4 million annual visitors. During his tenure, Johnson oversaw the renovation of the Fossil Hall, the construction of the Ocean Terrace Café under the life-size model of an ancient Megalodon shark, and the addition of accessible walkways leading to the museum’s National Mall entrance.
In celebration of the nation’s 250th birthday, Johnson presided over the installation of three, larger-than-life bronze bison flanking the South Entrance. The renovation of the museum’s historic auditorium is now underway.
Johnson has also been a champion of communicating science to a broader audience through popular books, lectures, museum exhibitions, documentaries, and collaborations with artists.
Ensuring the museum’s long-term financial health has been a top priority for Johnson. Since becoming director, he has raised over $300 million for the museum and grown its endowment by 450% percent – from $82.7 million to nearly $380 million.
