Wilhelm Bauer (December 23, 1822 - June 20, 1875) was the German inventor and engineer, who built several hand powered submarines. Wilhelm Bauer was born in Dillingen, Germany. His father was a sergeant of a Bavarian cavalry regiment. Because of this, Wilhelm Bauer, after an apprenticeship as a wood turner, joined the military as well. Working as an artillery engineer he witnessed the German - Danish war for Schleswig - Holstein (1848 - 1851). Seeing how the German northern coast lay under the blockade by the Danish navy, Bauer quickly developed a plan to build a new kind of ship to help break the blockade. To accomplish that, Bauer began studying hydraulics and ship construction. But before his studies could bear any fruit the troops of the German Confederation decided to withdraw and surrender Schleswig - Holstein to
the Danish. Bauer, however, was determined to realize his plan at any
cost and left service in the German army to join the forces of
Schleswig - Holstein. It
proved very hard for Bauer, who had a low military rank, to bring his
plan through the various instances of the military administration and
to gain funding to build his craft. He finally succeeded with the help
of Werner von Siemens and others and was granted a small sum of money to built a model of his submarine. Incendiary ships were
a well known concept in blockade breaking. A ship was loaded with
explosives and set free to drift into the enemy fleet, exploding at
contact. The incendiary diver was planned to work on a similar principle: It would dive under an enemy vessel, fix an electrically triggered mine to
its hull and escape, igniting the mine from a safe distance. The more
or less same technique was employed by all military submarine designs
of that time, like Julius Kröhl’s Explorer, the U.S.S. Alligator by Brutus de Villeroi and the famous Hunley, which became the first submarine to sink an enemy vessel. After
the model of the submarine, built by Bauer himself, proved to be
working, he was granted enough money to build a full scale submarine.
But the military authorities still were largely against Bauer’s plan
and forced Bauer to change his designs in order to reduce costs. The
finished Brandtaucher, built by August Howaldt of the later Howaldtswerke was
28 feet long, weighing about 70,000 pounds. As at that time no suitable
mechanical power system was available the submarine was powered by two
sailors turning a big tread wheel with their hands and feet. The third
crew member, the captain, was positioned at the stern of the submarine.
His job was to operate the rudders and other controls. Having arrived
under the target ship the captain would reach out through a gutta percha (rubber)
glove fixed to an opening of the hull, grab the mine located within
reach on the hull of the submarine and fix it on the target. Had the Brandtaucher been
built according to Bauer’s original designs, it would have achieved
submersion by filling several tanks with sea water. But in the changed
version the vessel itself was to be partly flooded with
water, thus rendering the submarine dangerously unstable. Also the
thickness of the hull and the dimensions of the pumps had to be greatly
reduced. First
trials of the submarine took place in December 1850. Although Bauer
wanted to make several improvements of the submarine, the military
ordered a public show on the 1st of February, 1851. This
public demonstration almost ended in a disaster. After reaching a depth
of 30 ft the craft began to lay down by the stern. As the submarine
sank down the thin walls could not take the water pressure any more and
started to crack. The water pressure proved too much for the weak pumps
and the propeller wheel was damaged when the vessel began to keel over.
The submarine slowly sank to the ground of the Kiel harbour.
For six hours Bauer and his sailors had to wait inside the sunken
craft, until enough water had seeped in. This increased the air
pressure inside the submarine and finally allowed the men to open the
blocked hatchway. As the submarine stayed buried on the ground of the
sea, its crew came to the surface unharmed. This was the first
submarine escape to be witnessed and reported. The sunken submarine was raised in 1887 and can now be visited at the museum of military history at Dresden, Germany (Militärhistorisches Museum der Bundeswehr). After the sinking of the Brandtaucher,
Bauer instantly began to make plans for an improved, larger submarine.
But the government of Schleswig - Holstein refused to support Bauer after
their bad experience with Bauer’s first submarine. So
Bauer left Schleswig - Holstein. In the following years he tried to
obtain support for his invention in several countries, like Austria - Hungary, the British Empire or France. Finally, in 1855, Bauer made a contract with the grand prince of St. Petersburg (Russia). During that year Bauer built his second submarine, the Seeteufel (Sea Devil) in St. Petersburg. Much less information is known about this submarine than of the Brandtaucher.
However, it is said to have been twice as long as its predecessor, its
iron walls 1/2' thick with 21 windows in them. It had three big
cylinders to hold water as diving ballast and was designed for a crew
of 12. Having learned from his first boat’s disaster, Bauer provided the Sea Devil with a newly invented rescue device: the diver’s chamber. Through this chamber, which worked like an airlock, divers could leave and enter the submerged vessel. The Sea Devil proved
to be a very good design. It made 133 successful diving runs within
four months. But during the 134th dive, the submarine got stuck in the
sand of the seafloor. By emptying the water cylinders with the pumps,
the crew managed to raise the submarine high enough so that the
hatchway was above the waterline. The whole crew (including Bauer) was
saved, but unfortunately, the submarine sank back to the bottom of the
sea. After the end of the sea devil Bauer
soon left Russia. When he realized he wouldn’t find support for another
submarine he took to other projects. In 1863 Bauer managed to raise a
sunken ship by means of inflatable balloons made of canvas. But all his
more ambitious plans failed because of a complete lack of funding.
Disappointed by this Bauer died in 1875 in Munich. It would be wrong to claim that the German submarine fleet of the world wars was directly descended from Wilhelm Bauer’s prototypes. The modern submarine began its history with the inventions of Simon Lake and John Philip Holland. The submarine pioneers of the 19th century however - de Villeroi, Monturiol, Hunley and
others - were well aware of Bauer’s invention and derived inspiration
and many ideas from it. And without these men, we wouldn’t have the
technically advanced submarines we have today. In 1960 the German navy Bundesmarine renamed a Type XXI submarine Wilhelm Bauer The
filmmaker from Kiel Zoran Simic described in his film “Submarine
Ingenieur”, the life and work of Wilhelm Bauer, and also the principles
upon which he built the “Incendiary diver”. In many 3D graphics
sequences he illustrates the functioning of the submarine. On the 3rd
of February 2008 the 57-minute version of the film “Submarine
Ingenieur” was shown in the local cinema, in the event centre KoKi, in
Kiel. In 1941 German director Herbert Selpin realized a biopic about Bauer with the title Geheimakte W.B.1 (Secret file W.B.1;
W.B = Wilhelm Bauer)), which was released in 1942. It was a propaganda
movie to further the submarine war. The plot was built on the novel Der Eiserne Seehund (The iron seal) from Hans Arthur Thies, published in 1941. |
