Bicentenary of the birth of Isambard Kingdom Brunel

Isambard Kingdom Brunel was a true genius of the Industrial Age, whose vision and daring produced some of the greatest engineering wonders of Victorian Britain. To mark the 200th anniversary of Brunel’s birth Royal Mail worked with eminent Brunel historians to select six examples from his incredible portfolio of work.


1st class - Royal Albert Bridge (1854-1857).
The magnificent Royal Albert Bridge, designed and built to carry the Cornwall Railway at a height of 100 feet across the waters of the River Tamar at Saltash, must surely be recognised as one of his most outstanding works. Its unique design and handsome proportions, set in an idyllic location between the hills of Devon and Cornwall, give an aura of grace and majesty all of its own. As the “Gateway to Cornwall” it forms a fitting and lasting memorial to this great Victorian engineer. The stamp features a steel engraving of the Royal Albert Bridge, Saltash by Cornish artist R T Pentreath.

40p - Box Tunnel (1836-1841). This was the most difficult engineering problem that Isambard Brunel had to solve when building the London to Bristol line. Positioned between Bath and Swindon, Box Hill consists mainly of limestone. Five miles east of Bath and still in use today, it was built to bring the Great Western Railway down to Bristol from Swindon. The first train passed through on 30 June, 1841. The stamp image is taken from a coloured lithograph West Entrance to Box Tunnel on the Great Western Railway by John Cook Bourne, 1846.

42p Paddington Station (1849-1854). Brunel was ambitious in the design of the GWR’s London terminus, which he was charged with rebuilding in 1849 to accommodate the crowds expected to converge on London for the 1851 Great Exhibition. He was asked to construct a flexible covered space without columns to accommodate the railway’s future needs and to outshine the London terminus of the GWR’s arch-rival, the Great Northern Railway, at Euston. In an age when the new railways were regarded as the acme of modernity and sources of future prosperity for provincial cities and towns, public interest in Brunel’s daring schemes for the GWR was intense. The stamp image is a photograph taken by York and Son between 1870 and 1890.

47p PSS Great Eastern (1858). The Great Eastern was designed by Brunel. She was the largest ship ever built at the time of her launch, and had the capacity to carry 4,000 passengers around the world without refuelling. She would only be surpassed in length in 1899 (by the SS Oceanic), and in tonnage in 1901 (by the SS Celtic). She was built in partnership with an experienced ship designer, John Scott Russell. Unknown to Brunel, Russell was in financial difficulties, and the two men disagreed on many details. It was Brunel’s final great project, as he collapsed after being photographed on her deck, and died a few days later. She was built by Messrs Scott, Russell & Co. of Millwall, London, the keel being laid down on May 1, 1854. She was launched on January 31, 1858. She was 692 feet (211 m) long, 83 feet (25 m) wide, 60 feet (18 m) deep (draught was 20 ft (6.1 m) unloaded and 30 ft (9.1 m) fully laden) and weighed 32,000 tons (her tonnage was 18,915). Little is known about this image apart from the fact that it is dated around 1860.


60p - Clifton Suspension Bridge (1831-1864).
The story of the Clifton Suspension Bridge, spanning the Avon Gorge, began in 1754 with the dream of a Bristol wine merchant, who left a legacy to build a bridge over the Gorge. A competition in 1829 was held to find a design, being judged by Thomas Telford, the leading civil engineer of the day. Telford rejected all the designs and submitted his own but the decision to declare him the winner was unpopular and a second competition was held in 1830. Isambard Kingdom Brunel, only 24 at the time, was eventually declared the winner and appointed project engineer – his first major commission. The image is taken from the lithograph Clifton Suspension Bridge by G Childs, after a sketch by S Jackson circa 1834.

68p - Maidenhead Bridge (1838). Maidenhead Railway Bridge carryied the main line of the Great Western Railway over the River Thames in Maidenhead, Berkshire. The railway is carried across the river on two brick arches, which at the time of building were the widest and flattest in the world. Each span is 128 feet (39 m), with a rise of only 24 feet (7 m). The Thames towpath passes under the right-hand arch (facing upstream), which is also known as the Sounding Arch, because of its spectacular echo. As built, Maidenhead Railway Bridge carried two lines of Brunel’s broad gauge track. Subsequently the bridge has been widened, and now carries the four lines of standard gauge track that make up the Great Western Main Line out of London Paddington Station. The image is taken from a colour lithograph of the Maidenhead Bridge by John Cook Bourne.

Anghel I. Saligny – 155 Years since his Birth

With the occasion of celebrating 155 years from the birth of a Romanian genius - Anghel I. Saligny, within the annual theme ROMANIAN POSTAGE STAMP DAY, Romfilatelia honors this event with the introduction into circulation of the postage stamps issue “Anghel I. Saligny – 155 Years since his Birth”.


The railroad line Adjud - Tg. Ocna with the first combined bridges in the country – highway and railway (1881-1882), the first grain silos in the world made of reinforced concrete in Braila and Galati (1888-1889), the bridge over Siret from Cosmesti (1888), the bridges complex in Fetesti-Cernavoda, the longest in Europe (1895), the arrangement of the harbor in Constanta (1889-1909), these are a few of the engineering works left by a famous Romanian: Anghel I. Saligny.

His father, Alfred Saligny, native from Alsacia has established before 1859 in Romania, Focsani, where he opened a boarding school – private education institution destinated to the young people whose parents with a high living standard wished their children to get consistent knowledges in the domains of literature and French language, in which he also had the position of teacher.

After the Union of the Romanian Principalities, the foreigners were asked to declare whether they wanted to become Romanian citizens, which Alfred Saligny done; so that his children as well: Anghel, Alfons and Sofia have acquired the Romanian citizenship.


One of the founders of the Romanian engineering, Anghel I. Saligny was born on 1854 at Serbanesti, in the county of Galati.

The primary school was attended at his father’s boarding school in Focsani. After finishing the secondary school in the same city, he attended the high school courses in Germany, Postdam together with his sister, Sofia.

In the period of 1870-1874 he studied the engineering within the Superior Technical School in Charlottenburg. He worked, under the supervision of professor G. Mahrtens, at the construction of the Cottbus-Frankfurt railway on Oder, and between the years 1877-1879, under the supervision of Gh. Duca, he worked at the construction of the Ploiesti-Predeal railway.
With the name of Anghel I. Saligny are related world premières in the field of construction engineering.

The most important work of the Romanian engineer, unanimously acknowledged, is the construction of the bridge complex at Fetesti-Cernavoda, which on its inauguration date was the longest bridge in Europe and the third in the world and also one of the metallic bridges with a wide opening in the world. In the accomplishment of this complex of bridges, Saligny has brought two great innovations: the new system of cantilever beams for the structure of the bridge and the use of soft steel instead of ball iron as construction material for the bridge decks.

The bridge that until 1976 will wear the name of King Charles I (renamed afterwards Eng. Anghel Saligny) has been built between the years 1890-1895. It has been inaugurated on September 26th 1895 by the Romanian monarch who wished to drive in the last silver rivet.

Being fully convinced of the durability of the bridge, Anghel I. Saligny stayed with the workers in a boat, under the bridge, while the first merchandise set of cars and a train with guests specially arrived from Bucharest passed upon it.

The complex of bridges, with a length of almost 4090 m, is formed of the bridge over the Danube (with an openings of 190 m and other four openings of 140 m, near a viaduct with 15 openings of 60 m, at 30 m over the Danube waters) and the bridge over the river arm Borcea (with three openings of 140 m, a viaduct with 11 openings of 50 m and a viaduct with 34 openings of 42 m).

18 centuries after the construction of the bridge of Apolodor in Damask, the banks of the Romanian Danube were again united by the bridge of Anghel I. Saligny.

Another two constructions of Anghel Saligny have been world-wide awarded, i.e. the reinforced steel silos in Braila and Galati. The silos, projected and constructed by Saligny in 1888 and 1889 had the capacity of 25000 tons of grains and the dimensions of 30 x 120 m at the base and 18 meters height. The walls of the hexagonal cells of the silos have been carried out in world premiere as well, of ground manufactured pieces, with form of plates. The prefabrication of the ground plates, the bracing and joint corners, the welding of the metallic bars and the mechanization on the assembling have represented another world - wide priorities.

A work which also bears the engineering signature of Saligny is the setting up of the Constanta harbor, which has been carried out between the years of 1889-1909. At the Constanta harbor, Saligny introduced for the first time in Romania the piles and the etched copper - plates made of reinforced concrete in the harbor constructions.

Today, in Romania when we speak about poetry, we say Eminescu, when we speak about sculpture we look towards Brâncusi, when we speak about music we hear the strings of Enescu´s violin, when we are in the plane which carries us over the clouds we think of Vuia and Coanda, and when we speak about bridges and cross over the Danube to the Romanian beaches, we remember Anghel Saligny.

Casimir Gzowski - Capex 78

Sir Casimir Gzowski was the first chairman of the Commission for the establishment of the Queen Victoria Falls Park, forerunner of the present Niagara Parks Commission. During his eight years charmanship (1885-1893), he was largely responsible for the original planning of the famed Niagara Parks System we enjoy today.

Sir Casimir also engineered the construction of the International Railway Bridge across the Niagara River, linking Fort Erie with Buffalo (1870-1873), considered to be one the North American continent up to that time.

Gzowski was born March 5, 1813, in St. Petersburg, Russia, of Polish parentage. He was exiled to the United States in 1833 for his part in the Warsow rebelion against Russia. In 1838 he became both a lawyer and a U.S. citizien; married Maria Beebe the next year. In 1841 he settled in Toronto as an engineer in the Canadian Department of Public Works and became a naturalized Canadian citizen in 1846. He engineered the construction of the Great Western Railroad from Toronto to Sarnia.



Gzowski was made a Colonel and Aide-de-Camp to Queen Victoria in 1879 and was knighted in 1890. He died in Toronto, Ontario, August 24, 1898, aged 85 years.

Gustave Alexandre Eiffel


Alexandre-Gustave Eiffel
(1832-1923), French engineer and builder, most famous for the construction of the tower in Paris that bears his name. Born in Paris, his family included artisans and timber and coal merchants. Eiffel was educated at the Lycée Royal in Dijon and the College Sainte-Barbe in Paris, and he graduated from the École Centrale des Arts et Manufactures in 1855, joining a company that produced steam engines. 

In 1858 the company was granted a contract to erect a railway bridge in Bordeaux. Eiffel oversaw the construction with such success that in 1866 he founded his own company and soon became known for his wrought-iron structures. Starting in 1872 he attracted foreign contracts, and in 1877 he erected over the Douro River in Porto (Oporto), Portugal, a steel arch bridge 160 m (525 ft) in height.


Eiffel's work combined expert craftsmanship and graceful design, qualities that are evident in the Garabit viaduct in France. Completed in 1884, it was for a time the highest bridge in the world, winning Eiffel's factory a worldwide reputation for excellence. Eiffel cast Frédéric-Auguste Bartholdi's colossal statue Liberty Enlightening the World, which was dedicated in New York in 1886. Soon after, he began work on his greatest project, the building of the Eiffel Tower. It was completed in 1889 for the celebration of the centennial of the French Revolution (1789-1799). The imposing tower—constructed of 7,000 tons of iron in 18,000 parts held together by 2,500,000 rivets—rises to a height of 300m (984 ft), and continues to dominate the Paris skyline. In the early 1890s Eiffel gave up the daily management of his business and became absorbed in the new science of aerodynamics.

Poles in the world

The Polish Post has just introduced two stamps devoted to Poles who lived and worked abroad, and did extraordinary things. They left a permanent image, making the name of Poland famous.


Ernest Malinowski, whose 100th anniversary of death will be celebrated on March 3rd this year, is the constructor of the famous Central Trans-Andean Railway in Peru. It is called a marvel of the engineering art of the 19th century. It is 218 km long (from Callao to Oroya) and most of it is located over 2000m over the sea level. It riches its highest peak in Ticlio: 4818m over the sea level, and this is why it is a railway located at the highest point in the world. A special sign placed there is presented on the FDC envelope accompanying the stamp. The stamp itself represents a portrait of Ernest Malinowski and a bridge over Verrugas canyon, belonging to the biggest constructions of this type in the world - it is 175m long and its height is 77 m.

   
Rudolf Modrzejewski, known in the United States as Ralph Modjeski, son of the famous actress, Helena, also became famous as a constructor of bridges. His most famous constructions include the Benjamin Franklin Bridge on the Delaware river in Philadelphia, which is presented in the second stamp. It was erected in 1926 and it had a record-breaking suspended span and elastic steel pylons 110m high. His work during the construction of the Trans-Bay bridge in San Francisco and in Quebec was also evaluated very positively.
