Description of (scientific/cultural/natural) heritage
Fig. 1a. Konkoly Observatory, Main Building (Balazs)
Miklós Konkoly-Thege / Nikolaus von Konkoly (1842--1916) studied Physics and Astronomy at the Universities of Budapest and Berlin. After graduation, in 1863, he went on a tour to visit the most prestigious observatories of Europa (Greenwich, Paris, Heidelberg and Göttingen). His next tour, seven years later, took him to visit not only astronomical observatories, but also the workshops of the most prominent instrument makers of his day (Sigmund Merz in Munich, John Browning in London and Thomas Cooke in York) (Vargha & Kolláth).

The O’Gyalla Observatory (now Hurbanovo in Slovakia) was founded in 1871 by the noble astronomer Konkoly as a private observatory in addition to his palace. He started his observations with a small 4-inch telescope and a meridian circle. He built a small dome for the 6-inch Merz refractor, used with a Zöllner spectroscope. In 1874, he built a 2.80-m-dome, enlarged in 1879, for his 10.5-inch Browning reflector (27cm) -- very remarkable for that time to acquire a reflector. In addition, he bought a Rheinfelder photoheliograph for photographing the Sun.
The main building was later given three additional domes. In 1881, the Browning reflector was replaced with a 10-inch Merz refractor.
Konkoly’s favorite topic was spectroscopy (comets and meteors), also photography, later photometry. Konkoly joined the international programme for stars brighter than 7.5mag by observing the zone between -15 degrees and 0 degrees. His catalogue with the results, based on Hermann Carl Vogel’s classification of the spectra, was published in 1887.

In the 1860s, a revolutionary transformation took place in astronomy, astrophysics was born. These new physical methods in astronomy -- spectroscopy/spectral analysis, photometry, astrophotography, and solar physics -- have stimulated the creation of a new branch of research, called astrophysics by Zöllner in 1865. Konkoly was one of the ten pioneers, who started astrophysics:
Karl Friedrich Zöllner (1829--1891), Hermann Carl Vogel (1841--1907), William Huggins (1824--1910), Joseph Norman Lockyer (1836--1920), Angelo Secchi (1818--1878), Pierre Jules César Janssen (1824--1907), Nikolaus Thege-Konkoly (1842--1916), and a little bit later William Henry Pickering (1858--1938), Julius Scheiner (1858--1913), Johannes Hartmann (1865--1936), and others. Konkoly had very close friendships with Vogel and Hartmann in Potsdam and with Max Wolf (1863--1932) in Heidelberg.

In 1890, Konkoly Thege was appointed director of the Meteorological Service. In addition, he organized a geomagnetic observatory in O’Gyalla, and made significant contributions.
In 1899, Konkoly Thege donated his private O’Gyalla observatory to the Hungarian State.
The Hungarian staff left when Chechoslovakia was formed in 1920. The council of Budapest allocated a property up in the hills just outside the city border for a new observatory. Everything was transferred to Budapest, Svábhegyi (Schwabenberg).
The first dome and the meridian house were ready in 1921, the main building in 1926. Finally, the large dome was ready by 1928. Since the order was made back in 1913 and advance was already paid, the Heyde firm in Dresden agreed to deliver the 60cm telescope for the original price, without adjusting it to inflation. The new Svábhegy Observatory was soon doing cutting-edge research.

Konkoly himself became the director, Radó Kövesligethy deputy director. Baron Béla Harkányi (1869--1932) was appointed as observer, Antal Tass (1876--1937) and Béla Szántó were assistant professors.
The research in Budapest had also like O’Gyalla the emphasis on photometry, especially the Ógyalla Catalogue of Variable Stars in two volumes (1916, 1935) was published.
Fig. 3. Radó von Kövesligethy (1862--1934) (Wikipedia)
Radó von Kövesligethy (1862--1934) studied in Vienna, made his habilitation in Budapest in 1889 (private lecturer), in 1897 he became an associate professor, in 1904 full professor for cosmography and geophysics.
He published 15 years before Max Planck (1858--1947), in 1885 in Hungarian and in 1890 in German, a first successful spectral equation of black body radiation (cf. Balázs 2004, 2007), derived with the following properties: the spectral distribution of radiation depends only on the temperature, the total irradiated energy is finite, and in addition, the wavelength of the intensity maximum is inversely proportional to the temperature -- eight years before Wilhelm Wien (1864--1928)!

Radó von Kövesligethy (1862--1934) studied in Vienna, made his habilitation in Budapest in 1889 (private lecturer), in 1897 he became an associate professor, in 1904 full professor for cosmography and geophysics.
He published 15 years before Max Planck (1858--1947), in 1885 in Hungarian and in 1890 in German, a first successful spectral equation of black body radiation (cf. Balázs 2004, 2007), derived with the following properties: the spectral distribution of radiation depends only on the temperature, the total irradiated energy is finite, and in addition, the wavelength of the intensity maximum is inversely proportional to the temperature -- eight years before Wilhelm Wien (1864--1928)!

Miklós Konkoly-Thege / Nikolaus von Konkoly (1842--1916) studied Physics and Astronomy at the Universities of Budapest and Berlin. After graduation, in 1863, he went on a tour to visit the most prestigious observatories of Europa (Greenwich, Paris, Heidelberg and Göttingen). His next tour, seven years later, took him to visit not only astronomical observatories, but also the workshops of the most prominent instrument makers of his day (Sigmund Merz in Munich, John Browning in London and Thomas Cooke in York) (Vargha & Kolláth).

The O’Gyalla Observatory (now Hurbanovo in Slovakia) was founded in 1871 by the noble astronomer Konkoly as a private observatory in addition to his palace. He started his observations with a small 4-inch telescope and a meridian circle. He built a small dome for the 6-inch Merz refractor, used with a Zöllner spectroscope. In 1874, he built a 2.80-m-dome, enlarged in 1879, for his 10.5-inch Browning reflector (27cm) -- very remarkable for that time to acquire a reflector. In addition, he bought a Rheinfelder photoheliograph for photographing the Sun.
The main building was later given three additional domes. In 1881, the Browning reflector was replaced with a 10-inch Merz refractor.
Konkoly’s favorite topic was spectroscopy (comets and meteors), also photography, later photometry. Konkoly joined the international programme for stars brighter than 7.5mag by observing the zone between -15 degrees and 0 degrees. His catalogue with the results, based on Hermann Carl Vogel’s classification of the spectra, was published in 1887.

In the 1860s, a revolutionary transformation took place in astronomy, astrophysics was born. These new physical methods in astronomy -- spectroscopy/spectral analysis, photometry, astrophotography, and solar physics -- have stimulated the creation of a new branch of research, called astrophysics by Zöllner in 1865. Konkoly was one of the ten pioneers, who started astrophysics:
Karl Friedrich Zöllner (1829--1891), Hermann Carl Vogel (1841--1907), William Huggins (1824--1910), Joseph Norman Lockyer (1836--1920), Angelo Secchi (1818--1878), Pierre Jules César Janssen (1824--1907), Nikolaus Thege-Konkoly (1842--1916), and a little bit later William Henry Pickering (1858--1938), Julius Scheiner (1858--1913), Johannes Hartmann (1865--1936), and others. Konkoly had very close friendships with Vogel and Hartmann in Potsdam and with Max Wolf (1863--1932) in Heidelberg.

In 1890, Konkoly Thege was appointed director of the Meteorological Service. In addition, he organized a geomagnetic observatory in O’Gyalla, and made significant contributions.
In 1899, Konkoly Thege donated his private O’Gyalla observatory to the Hungarian State.
The Hungarian staff left when Chechoslovakia was formed in 1920. The council of Budapest allocated a property up in the hills just outside the city border for a new observatory. Everything was transferred to Budapest, Svábhegyi (Schwabenberg).
The first dome and the meridian house were ready in 1921, the main building in 1926. Finally, the large dome was ready by 1928. Since the order was made back in 1913 and advance was already paid, the Heyde firm in Dresden agreed to deliver the 60cm telescope for the original price, without adjusting it to inflation. The new Svábhegy Observatory was soon doing cutting-edge research.

Konkoly himself became the director, Radó Kövesligethy deputy director. Baron Béla Harkányi (1869--1932) was appointed as observer, Antal Tass (1876--1937) and Béla Szántó were assistant professors.
The research in Budapest had also like O’Gyalla the emphasis on photometry, especially the Ógyalla Catalogue of Variable Stars in two volumes (1916, 1935) was published.
