5574 Seagrave           Discovered 1984 Mar. 20 by Z. Vavrova at Klet.
Frank Evans Seagrave (1860-1934) was an American amateur astronomer, who observed the Sun, variable stars, novae, comets and minor planets from his private observatory. He was a prodigious computer of orbits of minor planets and comets, including the 1910 return of 1P/Halley.
