On April 22, 2023 we celebrated 100 years of discovery with the Steward Observatory Dome and the 36-inch first “All-American” made reflecting telescope,” both still in use today. This telescope is part of the SpaceWatch® Program on Kitt Peak, which monitors objects in space that might present a hazard to Earth.

Celebrating 100-Years of Discovery!

Friends of Steward Observatory,

Our thanks to all of you who joined us this past Saturday to celebrate the 100th anniversary of the dedication of the “All American” 36-inch Telescope of Steward Observatory and our recommitment to the research, education, and outreach missions it generated.  We hope you had as much fun as we did

The 36-inch, then a “Telescope of Huge Size,” according to the Arizona Daily Star, was built thanks to the philanthropic gift of $60,000 by Lavinia Steward to the University of Arizona. This enabled Andrew Ellicott Douglass, the first Director of Steward Observatory, to build the University’s first major research telescope.   This was the start of our growth into a world-class Observatory and Department of Astronomy. It paved the way for other major research facilities at the University, and ushered in an era of transformational philanthropic giving to the University.

Today, in honor of our first century and the philanthropic legacy that shaped it, we ask you to consider making a donation that can stimulate a new century of growth that will make as much history as our first 100 years. Our goal is to secure 100 donations by the end of April 30.  We are going to have a time capsule, to be opened on the 200th Anniversary of the dedication, that will have memorabilia from our celebration this past week as well as the names of the donors that participate in this mini-drive — so please consider joining Lavinia Steward among the long line of donors that have enabled us to explore the Universe together.
