Russian astronomer, academician. 
Born in Poland. He began his scientific activity together with F.F. Schubert at the Observatory of the Academy of Sciences, then worked at the Pulkovo Observatory, was a professor at St. Petersburg University. In 1804, Vishnevsky was elected associate member of the Academy of Sciences, since 1807 he has been extraordinary, and since 1815 he is an ordinary academician of the Petersburg Academy of Sciences. 
Vishnevsky was an astronomer-observer, as they say, "from God". He possessed exceptional visual acuity, so that he could consider objects that were invisible to others. For example, in Petersburg, Vishnevsky observed a comet in 1807 until March 1808, i.e. a whole month after all the astronomers of Europe lost sight of her. He observed the comet of 1811 in Novocherkassk from July 31 to August 17, 1812, when all other astronomers could not even find it. German astronomer F.V. Bessel called Vishnevsky "a virtuoso in the field of observation and an inimitable researcher". 
The observations were carried out mainly in the winter months, since the rest of the year Vishnevsky spent on expeditions in Russia to determine the geographical location of its most important points.  He began his trips in 1806 and graduated in 1815. Having traveled from Libava to Yekaterinburg and from Mezen to Elbrus over the years, Vishnevsky, with all possible accuracy and thoroughness, determined the coordinates of about 250 points, including almost all provincial cities. 
Since 1822, Vishnevsky served as astronomer of the Admiralty Department of the Marine Ministry. From 1827, after the ministry was transformed, he became an astronomer at the Hydrographic Depot. 
In 1833, Vishnevsky took part in the headed by F.F. Schubert is a chronometric expedition in the Baltic region, which made it possible to determine with great precision the longitudes of many important navigation points for the Baltic Sea. 
The Pulkovo Observatory commemorated the famous astronomer-traveler by placing his portrait in one of his halls. Awarded the Order of St.Stanislav 1 degree. 
He died in St. Petersburg, buried in the Smolensk Lutheran cemetery. The grave is not preserved.
