The story
Founded by Ábrahám Ganz in 1844, in Budapest.1
The company was founded by Ábrahám Ganz in 1844. He was invited to Pest, Hungary, by Count István Széchenyi and became the casting master at the Roller Mill Plant (referred to as Hengermalom in Hungarian). In 1854 he began manufacturing hard cast railroad wheels in his own plant founded in 1844. The management of the steam mill paid a share of the profit to Ganz. This enabled him to buy, in 1844, land and a house for 4500 Forints in Víziváros, Buda castle district. Abraham Ganz built his own foundry on this site and started to work there with seven assistants. They made mostly casting products for the needs of the people of the city. In 1845, he bought the neighbouring site and expanded his foundry with a cupola furnace. He gave his brother, Henrik a job as a clerk, because of the growing administration work. He made a profit in the first year, and his factory grew, even though he had not yet engaged in mass production. In 1846, at the third Hungarian Industrywork Exhibition (Magyar Iparmű Kiállítás), he introduced his stoves to the public. He won the silver medal of the exhibition committee and the bronze medaille from Archduke Joseph, Palatine of Hungary.
During the Hungarian Revolution of 1848 the foundry made ten cannons and many cannonballs for the Hungarian army. Because of this, the Military Court of Austria impeached him. He got seven weeks in prison as penalty, but because of his Swiss citizenship he was acquitted of the charge.
Ganz recognized that, to develop his factory, he had to make products that were mass-produced. In 1846 the Pest-Vác railway line was built. At that time, European foundries made wrought iron rims for spoked wagon wheels by pouring the casts in shapes in sand, and leaving them to cool down. He successfully developed a railway wheel casting technology; it was the new method of "crust-casting" to produce cheap yet sturdy iron railway wheels, which greatly contributed to the rapid railway development in Central Europe. 86,074 pieces of hard cast wheels had been sold to 59 European railway companies until 1866. Consequently, this factory played an important role in building the infrastructure of the Hungarian Kingdom and the Austro-Hungarian Empire. At this time the agricultural machines, steam locomotives, pumps and the railway carriages were the main products. At the beginning of the 20th century, 60 to 80% of the factory's products were sold for export.
After the death of Abraham Ganz, the heirs entrusted the management of the factory to his direct colleagues at Ganz Művek: Antal Eichleter, Ulrik Keller and Andreas Mechwart, which then took the name Ganz & Co. The Ganz family sold the company, which consisted of five departments, and in April 1869 it was transformed into a joint-stock company, and continued its operations under the name of "Ganz és Társa vasontöde és Gépgyár Rt." (Ganz & Partners Iron Foundry and Machine Factory Co.) The technical director was András Mechwart, under whose direction Ganz became one of the most important groups of machine building companies in the Austro-Hungarian Monarchy after 1869.
At the end of the 19th century, the products of the Ganz and Partner Iron Mill and Machine Factory (hereinafter referred to as Ganz Works) promoted the expansion of alternating-current power transmissions.
Prominent engineers
Prominent engineers at Ganz works included András Mechwart, Károly Zipernowsky, Miksa Déri, Ottó Titusz Bláthy, Kálmán Kandó, György Jendrassik and Ernő Wilczek.
Revolution in the milling industry
The invention of the modern industrial mill (the roller mill) – by András Mechwart in 1874 – guaranteed a solid technological superiority and revolutionized the world's milling industry. Budapest's milling industry grow the second largest in the world, behind the American Minneapolis. The Hungarian grain export increased by 66% within some years.
Power plants, generators turbines and transformers
In 1878, the company's general manager András Mechwart founded the Department of Electrical Engineering headed by Károly Zipernowsky. Engineers Miksa Déri and Ottó Bláthy also worked at the department producing direct-current machines and arc lamps.

In 1878, the company began producing equipment for electric lighting and, by 1883, had installed over fifty systems in Austria-Hungary. Their AC systems used arc and incandescent lamps, generators, and other equipment.
Generators
The first turbo generators were water turbines which drove electric generators. The first Hungarian water turbine was designed by engineers of the Ganz Works in 1866. Mass production of dynamo generators started in 1883.
The missing link of a full Voltage Sensitive/Voltage Intensive (VSVI) system was the reliable alternating current constant voltage generator. Therefore, the invention of the constant voltage generator by the Ganz Works in 1883 had a crucial role in the beginnings of industrial scale AC power generation, because only these types of generators can produce a stable output voltage, regardless of the actual load.
Transformers
In cooperation, Zipernovsky, Bláthy and Déri (known as the ZBD team) constructed and patented the transformer. The "transformer" was named by Ottó Titusz Bláthy. The three invented the first high efficiency, closed core shunt connection transformer. They also invented the modern power distribution system: Instead of a series of connections they connected supply transformers in parallel to the main line.
The transformer patents described two basic principles. Loads were to be connected in parallel, not in series as had been the general practice until 1885. Additionally, the inventors described the closed armature as an essential part of the transformer. Both factors assisted the stabilisation of voltage under varying load, and allowed definition of standard voltages for distribution and loads. The parallel connection and efficient closed core made construction of electrical distribution systems technically and economically feasible.
The Ganz Works built the first transformers using iron plating of enamelled mild iron wire, and started to use laminated cores to eliminate eddy currents
In May 1885, at the Hungarian National Exhibition in Budapest, Deri, Blathy, and Zipernowski held a large-scale demonstration of what is widely regarded as the prototype of modern AC lighting systems. Their system used 75 transformers in parallel connection, supplying 1,067 incandescent Edison lamps from an AC generator that provided 1,350 V.
AC Power stations
In 1886, the ZBD engineers designed, and the company supplied, electrical equipment for the world's first power station to use AC generators to power a parallel connected common electrical network. This was the Italian steam-powered Rome-Cerchi power plant.
Following the introduction of the transformer, the Ganz Works changed over to production of alternating-current equipment. For instance, Rome's electricity was supplied by hydroelectric plant and long-distance energy transfer.
Electricity meters
The first mass-produced kilowatt-hour meter (electricity meter), based on Hungarian Ottó Bláthy's patent and named after him, was presented by the Ganz Works at the Frankfurt Fair in the autumn of 1889, and the company was marketing the first induction kilowatt-hour meter by the end of the year. These were the first alternating-current wattmeters, known by the name of Bláthy-meters.
Industrial refrigerators and air conditioners
In 1894, Hungarian inventor and industrialist István Röck started to manufacture a large industrial ammonia refrigerator (together with the Esslingen Machine Works) which was powered by Ganz electric compressors. At the 1896 Millennium Exhibition, Röck and the Esslingen Machine Works presented a 6-tonne capacity artificial ice producing plant. In 1906, the first large Hungarian cold store (with a capacity of 3,000 tonnes, the largest in Europe) opened in Tóth Kálmán Street, Budapest, the machine was manufactured by the Ganz Works. Until nationalisation after the Second World War, large-scale industrial refrigerator production in Hungary was in the hands of Röck and Ganz Works.
The contract between Ganz and Egypt in the 1930s played a key role in the development of cooling equipment: railcars delivered to Egypt were equipped with air-conditioning cooling systems. The collective of the Ganz factory (machine designers: Gábor Hollerung, Rezső Oláh, István Pfeifer, Prónai) designed and built the 3-cylinder, 20 kW compressors with freon refrigerant, air condenser and evaporator. The machine could also be converted to heat pump operation.
ICE engines and vehicles
The beginning of gas engine manufacturing in Hungary is linked to Donát Bánki and János Csonka but it is not clear that they ever worked for Ganz.
Ganz produced engines whose designs were licensed to Western European partners, notably in the United Kingdom and Italy.

Steam motors
The Ganz Company started to construct steam locomotives and steam railcars from the 1860s.
Between 1901 and 1908, Ganz Works of Budapest and de Dion-Bouton of Paris collaborated to build a number of railcars for the Hungarian State Railways together with units with de Dion-Bouton boilers, Ganz steam motors and equipments, and Raba carriages built by the Raba Hungarian Wagon and Machine Factory in Győr. In 1908, the Borzsavölgyi Gazdasági Vasút (BGV), a narrow-gauge railway in Carpathian Ruthenia (today's Ukraine), purchased five railcars from Ganz and four railcars from the Hungarian Royal State Railway Machine Factory with de Dion-Bouton boilers. The Ganz company started to export steam motor railcars to the United Kingdom, Italy, Canada, Japan, Russia and Bulgaria.
The World's first electrified main railway line in Italy
The Ganz Works, having identified the significance of induction motors and synchronous motors, commissioned Kálmán Kandó to develop them. In 1894, Hungarian engineer Kálmán Kandó developed high-voltage three-phase AC motors and generators for electric locomotives. The first-ever electric rail vehicle manufactured by Ganz Works was a 6 HP pit locomotive with direct current traction system. The first Ganz made asynchronous rail vehicles (altogether 2 pieces) were supplied in 1898 to Évian-les-Bains (France) with a 37 HP asynchronous traction system. The Ganz Works won the tender for electrification of the Valtellina Railway in Italy in 1897. Under the management, and on the basis of plans from Kálmán Kandó, three phase electric power at 3 kV and 15 Hz was fed through two upper wires and the rails.
The electricity was produced in a dedicated power station and the system operated for thirty years from 1902. Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than just a short stretch. The 106 km Valtellina line was opened on 4 September 1902, designed by Kandó and a team from the Ganz works. The voltage was significantly higher than used earlier and it required new designs for electric motors and switching devices. The three-phase two-wire system was used on several railways in Northern Italy and became known as "the Italian system". Kandó was invited in 1905 to undertake the management of Società Italiana Westinghouse and led the development of several Italian electric locomotives.
Invention of the Phase Converter
In 1918, Kandó invented and developed the rotary phase converter, enabling electric locomotives to use three-phase motors whilst supplied via a single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high-voltage national networks.
After World War I, at the Ganz Works, Kálmán Kandó constructed a single-phase electric railway system using 16 kV at 50 Hz. A similar system, but using 15 kV at 16.7 Hz, later became widely used in Europe. The main attribute of Kandó's 50 Hz system was that it was fed by the normal power network, so dedicated railway power stations became unnecessary. Because of the early death of Kálmán Kandó, László Verebélÿ continued the work for the Hungarian State Railways (MÁV).
Ganz-MÁVAG rail rolling stock
In 1959 Ganz merged with the MÁVAG company and was renamed Ganz-MÁVAG.
In 1976 Ganz-Mávag supplied ten standard gauge 3-car diesel trainset to the Hellenic Railways Organisation (OSE), designated as Class AA-91 and four metre gauge 4-car trainsets, designated as Class A-6451. In 1981/82 Ganz-Mávag supplied to OSE 11 B-B diesel-hydraulic DHM7-9 locomotives, designated as class A-251. Finally, in 1983, OSE bought eleven 3-car metre gauge trainsets, designated as Class A-6461. All these locomotives and trainsets have been withdrawn with the exception of one standard and one metre gauge trainset.
In 1982/83 Ganz-Mávag supplied an order for electric multiple units to New Zealand Railways Corporation for Wellington suburban services. The order was made in 1979, and was for 44 powered units and 44 trailer units, which entered service as the New Zealand EM class electric multiple units.
Ganz-MÁVAG Trams
Ganz-MÁVAG delivered 29 trams (2 car sets) to Alexandria, Egypt from 1985 to 1986.
Shipbuilding, Ganz - Danubius
In 1911, the Ganz Company merged with the Danubius shipbuilding company, which was the largest shipbuilding company in Hungary. From 1911, the unified company adopted the "Ganz–Danubius" brand name. In the beginning of the 20th century the company had 19 shipyards on the Danube and the Adriatic Sea in the cities of Fiume and Pola.
As Ganz-Danubius, the company became involved in shipbuilding before, and during, World War I. Ganz was responsible for building the dreadnought SMS Szent István, all of the Novara-class cruisers, all of the Tátra-class destroyers, and built diesel-electric U-boats at its shipyard in Budapest, for final assembly at Fiume. Several U-boats of the U-XXIX class, U-XXX class, U-XXXI class and U-XXXII class were completed. A number of other types were laid down, but remained incomplete at the war's end. Ganz-Danubius was contracted to build 2 of the 4 Ersatz Monarch-class superdreadnought battleships, the most ambitious and powerful warships Austria-Hungary attempted to build, but due to the outbreak of the war, construction of this class was postponed and eventually cancelled. By the end of the First World War, 116 naval vessels had been built by the Ganz-Danubius company. The company also produces transatlantic ocean liners for passenger lines Trieste - New York, Trieste - Montevideo, as a reflection of already formed wave of mass migration from Central Europe to America.
Aircraft
The first Hungarian "aeroplane factory" (UFAG) was founded by the Ganz Company and Weiss-Manfréd Works in 1912. During World War I, the company made many types of Albatros and Fokker fighter planes.
Before 1919, the company built ocean liners, dreadnought type battleships and submarines, power plants, automobiles and many types of fighter aircraft.
The world's first turboprop engine was the Jendrassik Cs-1 designed by the Hungarian mechanical engineer György Jendrassik. It was built and tested in the Ganz factory in Budapest between 1939 and 1942. It was planned to be fitted to the Varga RMI-1 X/H twin-engined reconnaissance bomber designed by László Varga in 1940, but the program was cancelled. Jendrassik had also designed a small-scale 75 kW turboprop in 1937.
