Biography

Nikolaus Alois Maria Vinzenz Negrelli, Ritter von Moldelbe (also: Louis Negrelli) (January 23, 1799 - October 1, 1858), was a Tyrolean civil engineer and railroad pioneer mostly active in parts of the Austrian Empire, Switzerland, Germany and Italy.

Biography

Alois Negrelli was born Luigi Negrelli as the seventh of ten children to an Italian-speaking father and a German-speaking mother in Fiera di Primiero (German Markt Primör) in the Dolomites. The village is situated in the Trentino (Trient), once the south of the County of Tyrol (then with the Austrian Empire, today in northern Italy). Being in part of Welschtyrolean heritage (southern Tyroleans with romanic roots), the father and one of his older sisters actively supported the Tyrolean Rebellion of 1809, led by Andreas Hofer against the occupation of their homeland by French and Bavarian troops. Alois's father was held prisoner for years, finally returned home in 1814. The family, having lost a substantial part of their wealth, struggled at first to enable good education and safe livelihood for Alois and his siblings. This toil was facilitated by governmental authorities in recognition of their commitment. Alois Negrelli received an Austrian scholarship and went to secondary school in Feltre in 1812, together with his brothers. He later studied in Padua and Innsbruck in 1817, the capital of the Crownland of Tyrol, and passed at the age of 21 in 1820.

Civil Engineering

After beginning his career in 1818 as assistant to the Department of Construction in Innsbruck, Austria, he also worked in Vorarlberg from 1825 onwards residing in Bregenz. Negrelli constructed the Gschwendtobel-Brücke in Lingenau, a covered wooden bridge still in existence, and earned a reputation for taking part in the channelisation of the Alpenrhein and of the various Austrian and Swiss interests connected therewith. He moved to Switzerland in 1832 and took part in the erection of various constructions in the Canton of St. Gallen. In 1835, Negrelli was called to Zurich, where he continued with similar activity, notably working on the Münsterbrücke (Munster Bridge) crossing the Limmat together with Ferdinand Stadler, who was responsible for the carpentry. Stone bridges were still built over a wooden timber frame at this time. He also created the new Kornhaus (granary) in 1839 which later became the first Tonhalle (concert hall) of Zurich. In 1895 it was replaced by a newly constructed second building for this purpose.

Railway Construction

Beginning in 1836 Negrelli started planning a first railway line in this country. The Swiss Northern Railway is built years later in 1846 from Zurich to Baden, Switzerland, under his supervision. At around this time he was also appointed to different governmental commissions, working for other cantons. During a journey to England, France and Belgium he, like many other engineers, studied recent advances in railway construction and subsequently published his ideas of adapting this technology to mountainous regions in papers, receiving wide attention in the industry. In 1837 he advocated the creation of the railway Innsbruck–Kufstein in Tyrol and made preliminary plans for it, which the used later project was based on.

Negrelli returned to working in Austria in 1840. He was chosen as General Inspector for the private Emperor Ferdinand Northern Railway, and the Northern State Railway in 1842. He was responsible for the construction of the railway lines from Vienna via Prague to the German border in direction of Dresden, and via Ostrava to the Polish border in direction of Kraków. Negrelli prepared the railway to the then Austrian Lviv and the extension to the Russian border further east. He led the construction of the Negrelli Viaduct between 1846 and 1849, a railway bridge crossing the Vltava (Moldau) river in Prague, with 1,110 m the longest bridge of its kind in Europe until 1910 Negrelli's authority in railway matters was of particular relevance in the process of decisions to have the mountainous Semmering railway built by a fellow engineer, Carl von Ghega, in 1848 and his advice was requested for projects by various other states like the Kingdom of Württemberg and the Kingdom of Saxony in Germany. In 1849, Negrelli was to travel to the then Austrian Kingdom of Lombardy–Venetia with the task to oversee work on public buildings, railways and telegraph lines, and heading a commission regulating traffic on the river Po. In 1850 he was awarded for his services and received a title of nobility with the designation Ritter von Moldelbe, chosen by himself in memory of his times working on the rivers Vltava/Moldau and Elbe. After arriving back in Vienna in 1855, Negrelli is appointed General Inspector of the newly founded Imperial Royal Privileged Austrian State Railway Company until 1857. Afterwards it should become the Staats-Eisenbahn-Gesellschaft (State Railway Company), one of the biggest railway enterprises of the Austrian Empire.

Channelisation Projects in Egypt

Negrelli, like many other engineers of his time, had thought about possibilities to build an artificial waterway to connect the mediterranean sea with red sea from 1836 onwards. In 1846 he had been invited by Barthélemy Prosper Enfantin to the Société d'Études du Canal de Suez and took part in the exploration tour to the isthmus of Suez in 1847. Because of the outbreak of revolutions of 1848 and the following years, and other circumstances the Société d'Études had to cease activities, Negrelli himself being sent to Lombardy–Venetia at that time.

In 1855 Negrelli was invited by Ferdinand de Lesseps to participate again, now in the International Commission for the piercing of the isthmus of Suez (Commission Internationale pour le percement de l'isthme des Suez). Consisting of thirteen experts from seven countries who were to examine the plans made by Linant de Bellefonds it had to advise on the feasibility of and on the best route for a canal project. Negrelli formed part of the surveying group travelling to Egypt in late 1855 and early 1856. In the final deliberations of the commission in Paris at the end of June 1856, his principal ideas of a canal without locks and a northern entry further to the west prevailed. A comprehensive final report was produced, including plans and profiles, according to which the Suez Canal was later to be built by the Suez Canal Company, established in late 1858 by Lesseps.

The Suez Canal project, as the first of its kind in modern age, caused headlines. Since the Commission Internationale had presented their report in 1856 critics were agitating against it to a great degree, among them Robert Stephenson, son of railway poineer George Stephenson. Negrelli and others declared active support. The quarrel between defenders and repudiators went on for a time, this exchange was followed by publications throughout Europe, especially in France, Austria and the United Kingdom. Negrelli was prevented from travelling to Egypt another time and meeting with Lesseps, who went to London, in June 1858. Feeling unpleasant he used his leave from work to stay in a health resort for recovery. On the way back, Negrelli was able to attend a congress on railway development held in Trieste before he arrived at home in Vienna. Already seriously ill by September, he managed to write one last reply on the comments of Stephenson. Negrelli's response was published in the Oesterreichische Zeitung (Austrian Gazette) on September 26th of 1858.

Alois Negrelli von Moldelbe passed away in the morning hours of October 1st of 1858 at age 59, probably from food poisoning causing bacterial infection. His death occurred only weeks shy of witnessing the establishment of the Suez Canal Company, and just half a year before the works on the canal project were to officially begin.

In his book about Transportation and Communication of Egypt Negrelli wrote in 1856 about the Suez Canal:

... The connection of the two seas by a maritime canal, shortening the route between Europe and the rich countries of the Old World located at the Indian Ocean, not only for the development of global trade but also for the increase of cabotage (domestical shipping) for Egypt, related to the prosperity of inbound welfare to this country so blessed, is an undeniable necessity.
