Rudolph E. Schild (born January 10, 1940), PhD is an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, who has been active since the mid-1960s. He has authored or contributed to over 250 papers, of which 150 are in refereed journals. He is married to mezzo soprano Jane Struss, who teaches voice at Longy School of Music.
Schild is a proponent of "magnetospheric eternally collapsing objects" (MECOs), an alternative to black holes. These results are most often published in the fringe Journal of Cosmology, an astronomy journal edited by Schild himself, while his other research is published in mainstream astronomy journals such as MNRAS and the Astronomical Journal.
