  • Yerkes Director Announcement
    Yerkes Observatory Appoints New Executive Director Yerkes Future Foundation Recruits Innovative Cultural Leader to Spearhead Growth, Fundraising & Expansion WILLIAMS BAY, Wis.—Yerkes Observatory, the birthplace of modern astrophysics and home of the world’s largest refracting telescope, today announced the appointment of its new executive director. Dennis Kois, an arts and sciences executive with more than two decades of experience transforming cultural organizations, will assume the position effective March 8, 2021. Mr. Kois’ appointment marks a milestone in realizing the Observatory’s ambitious expansion plan, which began when the Yerkes Future Foundation (YFF) secured ownership of the Observatory from the University of Chicago in 2020. A Wisconsin native, Mr. Kois has a track record of transformational leadership at premier cultural institutions across the United States, including: • design and digital media leadership positions at the Metropolitan Museum of Art in New York City and the Smithsonian Institution in Washington D.C.; • president and CEO of the Milwaukee Public Museum, Wisconsin’s largest museum and one of the oldest natural history and science institutions in the nation; • executive director of the prestigious deCordova Sculpture Park and Museum in Boston; • and most recently, executive director of the renowned Burchfield Penney Art Center in Buffalo, New York. “I’m elated and humbled to accept this once-in-a-lifetime opportunity to chart a new course for Yerkes Observatory. Our community has the chance to build on the observatory’s 124-year legacy of groundbreaking scientific research, discoveries, and education—and to share one of the Midwest’s best- kept secrets with new generations of explorers across the globe,” said Mr.
