Question: Which spiral galaxy was discovered by a British astronomer and composer of German and Czech-Jewish origin?
Context: A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in approximately two-thirds of all spiral galaxies.  Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.  The Milky Way Galaxy, where our own Solar System is located, is classified as a barred spiral galaxy. Frederick William Herschel, (German: "Friedrich Wilhelm Herschel" ; 15 November 1738 – 25 August 1822) was a British astronomer and composer of German and Czech-Jewish origin, and brother of fellow astronomer Caroline Herschel, with whom he worked.  Born in the Electorate of Hanover, Herschel followed his father into the Military Band of Hanover, before migrating to Great Britain in 1757 at the age of nineteen. NGC 4889 (also known as Coma B) is an E4 supergiant elliptical galaxy.  It was discovered in 1785 by the British astronomer Frederick William Herschel I, who catalogued it as a bright, nebulous patch.  The brightest galaxy within the northern Coma Cluster, it is located at a distance of 94 million parsecs (308 million light years) from Earth.  Unlike a flattened, disc-shaped spiral galaxy like the Milky Way, NGC 4889 has no visible dust lanes or spiral arms and has a smooth, featureless, egg-shaped profile that diminishes in luminosity with distance from the center.  At the core of the galaxy is a supermassive black hole that heats the intracluster medium through the action of friction from infalling gases and dust.  The gamma ray bursts from the galaxy extend out to several million light years of the cluster. A flocculent spiral galaxy is a type of spiral galaxy.  Unlike the well-defined spiral architecture of a grand design spiral galaxy, flocculent (meaning "fluffy") galaxies are patchy, with discontinuous spiral arms. Approximately 30% of spirals are flocculent, 10% are grand design, and the rest are referred to as "multi-armed".  The multiple-arm type is sometimes grouped into the flocculent category. Malin 1 is a giant low surface brightness (LSB) spiral galaxy, the prototype of LSB galaxies.  It is located 366 Mpc away in the constellation Coma Berenices, near the North Galactic Pole.  s of 2015 it is the largest known spiral galaxy so far discovered, with an approximate diameter of 650000 ly , six and a half times the diameter of our Milky Way.  It was discovered by astronomer David Malin in 1986 and is the first LSB galaxy verified to exist.  As such, it is also the first giant LSB galaxy discovered.  Its high surface brightness central spiral is 30000 ly across, with a bulge of 10000 ly .  The central spiral is a SB0a type barred-spiral. An intermediate spiral galaxy is a galaxy that is in between the classifications of a barred spiral galaxy and an unbarred spiral galaxy.  It is designated as SAB in the galaxy morphological classification scheme.  By definition, a galaxy is a congregation of stars held together by gravity.  The first intermediate spiral galaxy discovered is the Milky Way, by Galileo, in 1610.  He was the first person with a telescope powerful enough to make such a discovery.  Before Galileo, it was thought that all bright objects in the sky were either the planets in the Solar System, moons, comets, or stars.  Until the beginning on the twentieth century, astronomers did not know the size of the Universe, but speculated it to be about as big as the Milky Way.  In 1920, at the National Academy of Science, there was a big debate between Harlow Shapley and Heber D. Curtis on whether nebulae are small globular clusters surrounding the Milky Way, or separate galaxies located farther away.  Nothing was resolved at the debate; neither side was able to provide conclusive evidence to prove their side correct over their opponent.  In 1923, Edwin Hubble resolved the matter with a photograph that he took of the Andromeda Galaxy.  What he found in his photograph was a very bright light source pulsing at a certain rate, a Cepheid variable, located outside the Milky Way.  This can be used to determine the distance to it.  Hubble proved that the Universe was full of galaxies, and disproved that the Milky Way was the extent of the Universe.  There are many types of galaxies in the Universe, elliptical, barred spiral galaxies; they vary in shape and size, but on average spiral galaxies are the most abundant. Messier 74 (also known as NGC 628) is a spiral galaxy in the constellation Pisces.  It is at a distance of about 32 million light-years away from Earth.  The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy.  The galaxy's low surface brightness makes it the most difficult Messier object for amateur astronomers to observe.  However, the relatively large angular size of the galaxy and the galaxy's face-on orientation make it an ideal object for professional astronomers who want to study spiral arm structure and spiral density waves.  It is estimated that M74 is home to about 100 billion stars. NGC 2775 (also known as Caldwell 48) is an unbarred spiral galaxy with a prominent ring structure in the constellation Cancer.  This galaxy has a bulge and multiple spiral arms, on which few HII regions can be detected, implying recent star formation.  It was discovered by William Herschel in 1783. NGC 5713 is a peculiar, asymmetric galaxy in the constellation Virgo.  Although classified as a spiral galaxy by most galaxy catalogs, NGC 5713 galaxy is very different from most normal spiral galaxies.  While most spiral galaxies either have either two well-defined spiral arms or a filamentary spiral-like structure, this spiral galaxy has only one visible spiral arm in its disk.  This makes it a galaxy of the Magellanic type.  Gravitational interactions with the nearby spiral galaxy NGC 5719 may be responsible for producing the disturbed, asymmetric structure including the single spiral arm. NGC 4874 (Coma A) is a supergiant elliptical galaxy.  It was discovered by the British astronomer Frederick William Herschel I in 1785, who catalogued it as a bright patch of nebulous feature.  The second-brightest galaxy within the northern Coma Cluster, it is located at a distance of 109 megaparsecs (350,000,000 light-years) from Earth.  Unlike a disc-shaped spiral galaxy like the Milky Way, NGC 4874 has no extensive dust lanes or spiral arms and has a smooth, featureless, ball-shaped profile that diminishes in luminosity with distance from the center.  The galaxy is surrounded by an immense stellar halo that extends up to one million light-years in diameter.  It is also enveloped by a huge cloud of interstellar medium that is currently being heated by action of infalling material from its central supermassive black hole.  A jet of highly energetic plasma extends out to 1,700 light-years from its center.
