JOHANN See also:

HEVELIUS [HEVEL or H6WELCKE] (1611—1687)  , See also:German astronomer, was See also:born at See also:Danzig on the 28th of See also:January 1611 . He studied See also:jurisprudence at See also:Leiden in 1630; travelled in See also:England and See also:France; and in 1634 settled in his native See also:town as a See also:brewer and town councillor . From 1639 his See also:chief See also:interest became centred in See also:astronomy, though he took, throughout his See also:life, a leading See also:part in municipal affairs . In 1641 he built an See also:observatory in his See also:house, provided with a splendid instrumental outfit, including ultimately a tubeless See also:telescope of 150 ft. See also:focal length, constructed by himself . It was visited, on the 29th of January 166o, by See also:John II. and Maria See also:Gonzaga, See also:king and See also:queen of See also:Poland . See also:Hevelius made observations of sunspots, 1642—1645, devoted four years to charting the lunar See also:surface, discovered the See also:moon's See also:libration in See also:longitude, and published his results in Selenographia (1647), a See also:work which entitles him to be called the founder of lunar See also:topography . He discovered four comets in the several years 1652, 1661, 1672 and 1677, and suggested the revolution of such bodies in parabolic tracks See also:round the See also:sun . On the 26th of See also:September 1679, his observatory, See also:instruments and books were maliciously destroyed by See also:fire, the See also:catastrophe being described in the See also:preface to his Annus climactericus (1685) . He promptly repaired the damage, so far as to enable him to observe the See also:great See also:comet of See also:December 168o; but his See also:health suffered from the See also:shock, and he died on the 28th of January 1687, Among his See also:works were: Prodromus cometicus (1665); Cometographia (1668); Machin coelestis (first part, 1673), containing a description of his instruments; the second part (1679) is extremely rare, nearly the whole issue having perished in the conflagration of 1679 . The observations made by Hevelius on the variable See also:star named by him " Mira " are included in Annus climactericus . His See also:catalogue of 1564 stars appeared posthumously in Prodromus aslronomiae (169o) . Its value was much impaired by his preference of the See also:antique " pinnules " to telescopic See also:sights on quadrants .

This led to an acrimonious controversy with See also:

Robert See also:Hooke . In an See also:Atlas of 56 sheets, corresponding to his catalogue, and entitled See also:Firmament um Sobiescianum (1690), he delineated seven new constellations, still in use . Hevelius had his See also:book printed in his own house, at lavish expense, and himself not only designed but engraved many of the plates . See J . H .
