Ludwig Dürr

Ludwig Dürr was the chief designer of all airships built by the Zeppelin Company with the sole exception of the very first zeppelin, LZ-1, which he helped build.

Count Ferdinand von Zeppelin made Dürr his chief designer when the Count’s first engineer, Kübler, who had designed LZ-1, refused to fly in his own creation.   After Zeppelin was forced to dismantle his first ship and cease operations for lack of funds in 1900, Dürr was the sole employee who continued to work for Zeppelin, and he remained with the Zeppelin Company until 1945.

In addition to working as a designer, Dürr was also trained as an airship pilot, and he commanded the zeppelins LZ-5 (Z-II), LZ-6, and LZ-7 Deutschland.

In the very first ship he designed, LZ-2, Dürr made major and important engineering improvements, such as replacing the weak tubular girders of LZ-1, which had allowd the hull to twist and hog in flight, with triangular girders which provided the rigidity necessary for a successful airship.

Dürr was known for his conservative to approach to design, which was partly out of conviction, and partly because he recognized that his strength was in empirical design — learning from trial-and-error and previous experience — rather than a more theoretical or mathematical approach, which he left to others (such as Karl Arnstein for stress analysis, and Paul Jaray for aerodynamic design).  But there is no doubt that Dürr’s commitment to using time-tested, tried-and-true designs resulted in strong, sturdy ships.

I read in the Wikipedia article on Ludwig Dürr that there is a high trail in the Verwall Alps named after him, and I checked into this for more details. There is a trail system in Verwall region in Tyrol, Austria connecting several lodges (huts) that provide overnight accommodations for hikers. The trails vary in difficulty with the Ludwig Dürr Weg being the most difficult requiring alpine experience in the hiker.

The trail begins at the lodge called the Friedrichshafen Hut. This hut and property was purchased in 1922 by the Deutscher Alpenverein (DAV) Sektion Friedrichshafen a group of then some 60 mountain enthusiasts founded in 1911 by Count Ferdinand von Zeppelin Jr (nephew to the airship inventor) who was its first chairman. Another founding member was Ludwig Dürr who served as the section chairman from 1920 to 1945. Ludwig Dürr was the initiator for the acquisition of this property. Also, Ludwig Dürr had traversed through the uncharted areas in the Verwall region with other DAV members and established the trail that was to eventually bear his name.
The Friedrichshafen Hut has 48 beds, a panoramic Alpine view, and a family atmosphere. A bronze bust of Ludwig Dürr on the terrace overlooks the trail named after him. Here is a brief article on Ludwig Dürr’s alpine work:

Currently DAV has grown to some 4500 members. It is dedicated to a variety of mountain activities, youth, family and senior groups, Alpine conservation and education. Here is the DAV website (the English translations are decent):

A brief history of the DAV is recounted here:

The Ludwig Dürr Weg (Way) is about a 6.5 to 7 hour hike through steep terrain, ice and snow fields with a glacier crossing and ends at the lodge called the Darmstadt Hut. It is suggested that hikers have crampons, icepicks and the required experience for traversing glaciers. The following website gives an overview of the trail’s difficulty and the experience required:

This website gives a profile of the elevations along the Ludwig Dürr:

Here is a link to a topographical map and elevation profile:

This link describes a hike through the Verwall/Paznauner trail system of which the Ludwig Dürr trail is listed as the 6th Stage:

“At this stage we are dealing with a really high alpine climbing to do with glacial transition, which all the conditions necessary demands. This means in late summer ice ax and crampons may be required. Thus, it is the absolute hardest part of Paznauner altitude trail and requires alpine experience and knowledge.”

Here is an excerpt from a trekking forum. The photographs are awesome:

“On Fri we made the Ludwig Dürr-way (GPS Track) to Darmstädterhütte. It was really something. Snowfield to snowfield incl. Smaller climbing notes and a glacier crossing. This can be quite annoying if you have neither Leggings NEN ice pick here.”

Although of these links have English translations available some of them require a little browsing to find them.
