ostrow

Marshall E. Ostrow

Writer, editor of Tropical Fish Hobbyist Magazine. On a personal note, I (rjs) recall in the may or june issue in 1974 he wrote the prhase "the llogic is flawless even if the premises are open to suspicion" which I thought was particularly elegant for an amateir tropical fish magazine. More people should learn to write like Marshall Ostrow.
