Grote Reber (1911 - 2002)
For three years in the early 1950s, the "Father of Radio Astronomy" Grote Reber toiled on Haleakala, building a rotating antenna that became the first high-altitude telescope in Hawai‘i. He also wrote papers on the ionosphere, the atmosphere and the age of Haleakala lava flows. He left Hawai‘i to pursue radio astronomy in Australia and the mainland United States.
Upon Reber's death in 2002 at age 91, the executors of his estate arranged for a portion of his cremated remains to be sent to the facilities he helped establish around the world. The ashes and plaque now reside at Reber's old control building, still standing on Haleakala.
