		He was born at Altona then part of Denmark, in what is now Germany, the son of Jacob Struve (1755–1841), and was the second of an entire family of astronomers through five generations.
		In addition to Otto Wilhelm von Struve, other children were Heinrich or Genrikh Vasilyevich Struve (1822 – 1908), a prominent chemist, and Bernhard Vasilyevich Struve (1827 – 1889), who served as a government official in Siberia and later as governor of Astrakhan and Perm.

	Struve 1321 / Gl 388 AB
		According to radial velocity measurements which have been since disproved, both Struve 1321 A and B, each, were once suspected of having an unseen companion (Helmut A. Abt, 1971 private communication to Kyongae Chang; Morbey and Griffin, 1987; and possibly L.G. Romanenko, 1989).
		Struve 1321 B is a orange-red main sequence dwarf star of spectral and luminosity type K7-M0 Ve.
		Since Struve 1321 A and B are sort of like distant cousins to Sol, some speculate whether they might just be bright enough to support Earth-type life on a planet lucky enough to orbit in its water zone.

	Struve 2398 AB
		Struve 2398 is too dim to be seen with the naked eye.
		In 1958, Wilhelm F. Rabe (1893-1958) derived a period of 346 years with an average distance of 42 AUs (based on updated parallax) and an eccentricity of 0.55, so that the stars swing between 19.0 and 65.3 AUs apart.
		Struve 2398 B is a flare star, like UV Ceti (Luyten 726-8 B) shown flaring at left.

		The German-Russian astronomer Friedrich Georg Wilhelm von Struve (1793:1864) was similarly plotting the position of "Vega", the fourth brightest star in the sky.
		The third effort was conducted by the German astronomer Friedrich Wilhelm Bessel (1784:1846), who was plotting the position of the star "61 Cygni".
		As determined by the German physicist Wilhelm Wien (1864:1928) in 1893, the peak frequency corresponded to the temperature of the fl body.

		In 1846 Struve published his observations of the absorption of stellar light in the galactic plane, which he correctly deduced to be caused by the presence of interstellar material.
		Struve made significant contributions to geodesy with his survey of Livonia 1816-19 and his measurements of the arc of meridian 1822-27.
