Diane Knutson, President | USA
Bienvenidos. Welcome. 欢迎.Velkommen.
A pivotal moment occurred in Diane’s life while working as a National Park Ranger. During her night sky program around the campfire, a child from the audience asked, “What happens if we don’t stop light pollution?” Not having a good answer, Diane’s mission became to reverse the harmful impacts caused by using artificial light at night. Diane began efforts to preserve night sky quality worldwide and address light pollution. A grassroots organizer, she brought together personnel from city councils, public utilities, businesses, organizations, and National Parks.
Diane emphasizes, “Night sky quality is important, and it’s about much more than viewing the cosmos. While access to the night sky is marvelous in itself; natural night conditions are essential to the wellbeing of all life on Earth.”
Diane began to advocate for the reduction of light pollution by connecting policymakers with night-sky preservation advocates within South Dakota, founding an IDA Chapter in South Dakota. The chapter coordinates events in the Black Hills (Paha Sapa), such as the Mickelson Star Trail nights and city-wide dark sky festivals.
Diane earned a Master’s Degree from the University of Iowa, and a Bachelor’s Degree in Community Health Education from the University of Nebraska. Diane believes some of her best education comes from connecting with others under a sky full of stars. “The stars have great knowledge, and they have it for you.”
As a business owner and currently an involved parent, Diane brings business experience and leadership skills to the board.
Diane’s faith, family, and friends serve vital roles in fulfilling her life’s purpose. Diane is reminded of Matthew 2:10. “When they saw the star, they were overjoyed.” and finds assurance in Psalm 19. “.…night after night they (heavens) reveal knowledge.”
Diane wants us to remember that a portion of our time belongs under a star-filled sky.
Tom Reinert, Vice-President | USA
Tom is a retired Washington, D.C. lawyer who spent most of his career representing airlines and railroads in labor and employment matters, including extensive experience translating scientific experts for lay decision-makers. He is a graduate of Harvard College and the Harvard Law School. His environmental activism included a decade fighting water pollution with local riverkeeper organizations on the Chesapeake Bay in Maryland. In 2013, seeing the Andromeda Galaxy for the first time with his naked eyes from atop Kitt Peak rekindled an interest in astronomy and a desire to eliminate light pollution. Currently residing in Northern Virginia, he and his wife Chris travel extensively in the Western United States seeking dark sky locations. For several years he has assisted IDA as a volunteer on legal and public policy issues at the national level.
Brad Schlesselman, Treasurer | USA
As Senior Research Engineer with Musco Lighting, Brad has worked closely with IDA for many years helping to establish benchmarks and best practices for exterior lighting that align with IDA’s purpose and goals. Brad has helped spearhead Musco’s decades-long mission of controlling and applying light in ways that significantly reduce glare, spill, and skyglow; and is a firm believer that the best outdoor lighting systems are designed in a way that’s equally focused on preserving darkness as on illuminating the intended area. Lighting at night, when necessary, can co-exist with protecting the enjoyment of observing the dark night-time skies.
Connie Walker, Secretary | USA
Connie Walker is an astronomer dedicated to dark skies education as well as measurement and mitigation.
