james cook
captain james cook discovered the southern eight islands of the sandwich islands group in 1775, although he lumped the southernmost three together, and their status as separate islands was not established until 1820 by fabian gottlieb von bellingshausen. the northern three islands were discovered by bellingshausen in 1819. the islands were tentatively named "sandwich land" by cook, although he also commented that they might be a group of islands rather than a single body of land. the name was chosen in honour of john montagu, 4th earl of sandwich, first lord of the admiralty. the word "south" was later added to distinguish them from the "sandwich islands", now known as the hawaiian islands.

compounds closely related to [cr(ch)] had been prepared many years before fischer's work by franz hein by the reaction of phenylmagnesium bromide and crcl. hein's reaction affords cationic sandwich complexes containing bi- and terphenyl, which baffled chemists until the breakthrough by fischer and hafner. (indeed, although harold zeiss and minoru tsutsui of yale university had earlier proposed the "sandwich" structure, they were unable to convince skeptical journal referees to publish their manuscript until fischer and hafner's results were made known.) fischer and seus soon prepared hein's [cr(ch-ch)] by an unambiguous route, thus confirming that hein had unknowingly discovered sandwich complexes, a half-century ahead of the work on ferrocene. illustrating the rapid pace of this research, the same issue of "chem. ber." also describes the mo(0) complex.
