the Observatory and its difference in longitude from Paris, and in 1751 took part
together with the observers at the Cape, London, and Berlin in corresponding
observations for determining the parallaxes of the sun and moon, and observed
in Stockholm the transits of Venus in 1761 and 1769. The fame he enjoyed
among his contemporaries was chiefly founded on the tables that he constructed
for the satellites of Jupiter.
At the beginning of the 19th
century D. Melanderhjelm (1726/
1810) of Uppsala initiated a new
mensuration of latitudes in Lappland
(1801/03), which was carried out by
J. Svanberg (1771/1851). Several
decades later (1850/51) this was
followed by a Swedish-Russian
men-snration of latitudes from Torneå
to Fuglenæs (near Hammerfest in
Norway), carried out by N. H.
Selander (1804/70) in Stockholm, J.
M. Agardh (1812/62) in Lund, and
I). G. Lindhagen (born 1819), the
last having been appointed at the
Pulkova Observatory and taking part as
Russian delegate. Lindhagen, later on
appointed at the Stockholm
Observatory, in conjunction with Fearnley in
Christiania and Schjellerup at
Copenhagen, carried out mensuration of
longitudes between the Observatory at
Stockholm and those of the towns above
mentioned. — From the very
beginning of the century
geodetic-topographical work was taken up in Sweden with increasing interest. S. A. Cronstrand
(1784/1850) and K. P. Hällström (1774/1836) actively took part in this by
carrying out the determination of astronomical places for the work of mapping
out Sweden. Selander and still more P. G. Rosén (born 1838; professor at the
General Army Staff’s Topographical Department in Stockholm) have carried out
and advanced geodetical works in Sweden, which since 1863 entered as an integral
part in the »International European measurement of Latitudes».
On a par with the above-mentioned measurements and observations, the work
of scientific research has been most successfully carried on. E. Prosperin (1739/
1803) is known for a table of comets often used and containing a register of the
older comets from 837 A. D. down to 1795, together with determinants for the
same in their nearest positions in respect to the earth. A. Bredman (1770/
1859) published in the middle of the century an extensive manual entitled
>Principles of Theoretical Astronomy». G. Svanberg (1802/82) has done
excellent service in Swedish astronomical research by erecting a new Observatory in
Uppsala, completed 1853. H. Schultz (1823/90) was a zealous observer, who
acquired fame by his »Micrometrical observations of 500 Nebulæ», by his
measurements of star-groups — the so-called »clusters» — and by his taking part,
on behalf of Uppsala, in the corresponding observations on the planet Mars in
1862, for determining the solar parallax. — A new Observatory was erected at
Lnnd in 1860 nnder the direction of D. M. A. Möller (1830/96), renowned for
his researches with reference to the Faye-Möller comet; and the Stockholm
Observatory was restored and enlarged 1877, after the Finnish astronomer P. H.
Anders Celsius.
