11768 Merrill           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Paul W. Merrill (1887-1961), a Mt. Wilson Observatory spectroscopist, was the first to detect a short-lived isotope, of technetium, in the atmospheres of stars, thus confirming that nucleosynthesis must occur in stars.
