Otto Wilhelm von Struve was a nineteenth century Russian space expert who spearheaded the investigation of twofold stars and contributed incredibly to our cutting edge comprehension of astronomy. Child of the Russian space expert Friedrich Georg Wilhelm von Struve, Otto emulated his dad’s example. He was a virtuoso in his time; finishing school instruction at 15 years old and college training at 20 years old.

During his time at the Imperial University of Dorpat, Otto Wilhelm von Struve helped his dad list the northern skies. Otto Wilhelm alone is credited with finding an expected 500 twofold star frameworks alongside point by point distributed estimations of their circles. All through his lofty profession, he finished the most precise estimation of the world’s bend, known as the Struve Geodetic Arc, arranged the rings of Saturn and found the second moon of Uranus.

Champ of a Gold Medal of the Royal Astronomical Society and an individual from the Russian Academy of Sciences, Otto Wilhelm’s commitment to the field of cosmology is unmatched. After his passing, the family’s name kept on being well known in stargazing. His children: Ludwig and Hermann, both proceeded to end up effective stargazers and his grandson, Otto Struve, too was a celebrated space expert.

Adolescence and Early Life

  • Otto Wilhelm von Struve was conceived on May 7, 1819, in the then Russian Empire city of Dorpat (present day Tartu, Ukraine). He was the third of the eighteen youngsters destined to Friedrich Georg Wilhelm von Struve and his significant other Emilie Wall.
  • At 15 years old, he finished his essential training in Dorpat. While too youthful to even think about attending college, he was welcome to the Imperial University of Dorpat to tune in on talks. While going to college, he helped his dad who worked at the Dorpat Observatory.
  • When he graduated at 20 years old in 1839, he was designated Assistant Director at the recently finished Pulkovo Observatory.
  • In 1841, he got a Masters of Astronomy from the University of St. Petersburg.


  • In 1841, he started his first autonomous research, testing William Herschel’s hypothesis of the close planetary system pushing toward the Hercules group of stars.
  • In 1842, he started his exploration on twofold stars for which he would later wind up renowned.
  • From 1843 – 1844, he was a piece of the group that did longitude estimations between Altona, Greenwich and Pulkovo, which depended on enormous relocation of chronometers over the Earth surface.
  • In 1844, he committed himself to contemplating the sun, estimating its speed to be 7.3 km/s. While the speed estimated was observed to be erroneous in an investigation completed in 1901, Otto Wilhelm was right as he would see it that the sun was much more slow than most stars in the night sky.

  • In 1851, he distributed notes of his perceptions of Uranus’ moons, Ariel and Umbriel, alongside discoveries on Neptune.
  • At the point when his dad became sick in 1858, Struve took on the board of the Pulkovo Observatory. In 1862, he moved toward becoming Director of the observatory and remained so until his retirement in 1889.
  • In 1861, he exhibited his hypothesis on how stars are shaped from interstellar issue to the Academy of Sciences.
  • In 1872, he sorted out the recently opened Tashkent Observatory.
  • In 1874, he traversed Asia, Persia and Egypt to watch Venus’ circle.
  • From 1879-1884, he helped redesign the Pulkovo Observatory. Upon its fruition in 1885, the observatory held the world’s biggest telescope with a 30 inch refracting focal point.

Real Works

  • Proceeding with his dad’s work, Otto Wilhelm von Struve assembled the Pulkovo Catalog of Stellar Coordinates, an inventory of thousands of twofold stars.
  • In 1847, he co-found Uranus’ subsequent moon, Umbriel, alongside William Lassell.
  • In 1851, while concentrating a sun oriented shroud, he inferred that waves falling off the sun were in actuality plasma, not an optical hallucination. Sunlight based crown was a disagreeable thought at the time yet was later demonstrated genuine.
  • In 1852, he finished the triangulation of the Meridian circular segment from Hammerfest to Nekrasovka. This exact estimation of separation, including the arch of the earth, was named the Struve Geodetic Arc.
  • During the 1850s, he quantified Saturn’s rings and found its darker internal rings. The naming framework he developed for the rings is as yet utilized today.

Grants and Achievements

  • In 1850, Otto Wilhelm von Struve was granted the Gold Medal of the Royal Astronomical Society for his 1840 production ‘The Determination of the Constant of Precession with Respect to the Proper Motion of the Solar System’.
  • From 1852 to 1889, he was an individual from the Russian Academy of Sciences
  • In 1913, Asteroid 768 was named Struvena to pay tribute to 3 cosmologists of the Struve family, in particular, Friedrich Georg Wilhelm, Otto Wilhelm and Otto.

Individual Life and Legacy

  • His first marriage was to Emilie Dyrssen. Together, they had six youngsters, two girls and four children. Emilie passed on in 1863.
  • He wedded his subsequent spouse, Emma Jankowsky, in the mid-1860s. Together, they had one little girl.
  • Two of his children, Ludwig and Hermann, proceeded with the family heritage and progressed toward becoming cosmologists. Of the other two, one worked for the Ministry of Finances and the different as a geologist.
  • In the wake of resigning in 1889, Struve lived in St. Petersburg, incorporating his notes and trading letters with different space experts. He was enamored with movement and regularly visited Italy and Switzerland.
  • In 1895, he ventured out to Germany where he turned out to be sick and chosen to remain there.
  • Otto Wilhelm von Struve passed on April 14, 1905 in Karlsruhe, Germany.
