Halcyon evolved from S&R Foundation, a nonprofit organization that supports talented individuals with great potential and high aspirations in science, art and social entrepreneurship. Arising from the Foundation’s success and recognizing unique opportunities to advance the missions of different types of fellows, Halcyon began operating independently as a public 501(c)(3) organization in 2017.
Halcyon headquarters are located in Halcyon House, a historic estate in the heart of Washington, D.C.’s Georgetown neighborhood.
Halcyon House was built in 1787 by First Secretary of the Navy, Benjamin Stoddert, with gardens designed by Pierre L’Enfant, DC’s original architect. While the property’s historical significance is grounded in the past, the house has been transformed to meet the needs of forward-thinking individuals solving modern-day challenges. Halcyon House is steps away from one of the most vibrant areas in the nation’s capital where students, residents and tourists alike mingle and interact in the shops, galleries, cafes and restaurants.
