How can a tourist obtain an 'authentic' duelling scar?

The short answer is: you can't.

As an "honorary" member of a Burschenschaft, I fought two duels in Freiburg in 1988, leaving me with a prominent Schmiss on my right cheek (11 stitches) and a small one (one stitch) that probably wont be noticeable even if and when I go bald. I've probably witnessed over 100 duels. Though a lot of time has passed since I did this, I suspect things haven't changed very much.

Here's what you would need to do to even have the opportunity to get a duelling scar:

1. Join a duelling fraternity, or Schlagende Verbindung. Though I would later be offered full membership, I was able to become an "honorary" member of a Burschenschaft by virtue of a German great-great-grandmother (and because my father knew a German Navy officer who was an alumnus). A Burschenschaft is typically not going to admit you if you're not German. For the Burschenschaft that I belonged, you had to have completed your Wehrdienst, or compulsory military service - those who chose non-military service (at a hospital or rest home, etc) could not join. So you'd need to find a Landsmannschaft or some other duelling organization that would let you join. Most Verbindungen are NOT of the duelling type. You have to be a student at the university in order to join, but foreigners are more welcome in the Landsmannschaft and Corps organizations.

2. After joining, you would need to do a lot of training before you would be approved for a duel. Its all about correct form and style - the objective is actually NOT to slice open the other guy (nor is it to get hit yourself !!) - and maintaining it no matter what happens during the duel. Typically you'll have your "basic" duel ("Fuchs Partei") in which only basic strikes are allowed; the "Burschen Partei" is the second type of duel, in which nifty things like horizontal blows are allowed. Training for this kind of duel typically takes a year.

3. In a basic duel, often no blood is even drawn - and because the strikes must come only from above (in Freiburg - other universities can differ in their protocol), even if you are hit, the scar likely wont be visible afterwards. Its not until the advanced class of duels that things get interesting - the cheeks and foreheads (and top of the ears) are vulnerable to horizontal blows, which are much more difficult to defend against. Now, I'm sure someone, somewhere, at some point, actually WANTED to get hit during a duel. However, you're OBLIGATED to perform at your best, so willfully allowing your guard down in order to receive a sharp hit would be an egregious breach of protocol. But by the time you've prepared for an advanced duel, your training simply kicks in - there's no time to think about your reactions because of the extremely fast alternation of strikes.

4. As with every endeavor in life, people will have different skill levels. So opponents are carefully chosen by a council of representatives from different Verbindungen (you never duel someone from your own) and you will face someone the same height, speed, and strength. You don't get to choose your opponent, and you don't go around challenging others to duels any longer. Duels are carefully arranged and there is no antagonism between opponents.

Let me comment on a few other topics in the OP :

Duels are categorically NOT public events, and instead take place inside a Verbindungshaus, in a large room that can accommodate the duellists, their seconds, the guy who cleans off your sword after each round, the doctors, and many observers. Attendance will be restricted to only those from other local duelling organizations - recognizable by the unique color band you wear across your chest as well as your matching hat. If you're not from a Schlagende Verbindung, wearing your colors (and a jacket and tie), you won't be allowed in. Period.

There are no publicly announced duels.

Duels are not fought with sabres any longer (sabres have curved blades) but with straight blades of varying weights about 1m long. Only the tip and about a third of the blade is sharpened, on both sides. Its entirely possible to hit someone with the flat part of the blade, which actually hurts more than getting hit with the sharp part. A blade ("Klinge") is used for only one duel.

"I'm aware that I could go to a doctor or even do it myself….but this would not be authentic…"

You are correct. (Hmmm)

"Protective gear in modern times is nowhere near as baroque…"

Actually, Mark Twain's description is pretty spot-on - though most serious duelling groups will have made an investment in chainmail vest ($$$), which gives a lot more freedom of movement than conventional old leather. Also its easier to clean the blood off.

The "iron goggles that project an inch or more" nowadays have a nose protector that can be attached, but otherwise probably look the same as when Mr. Twain described them. A leather strap holds the goggles to your head, and its cinched very tight to prevent a blade from taking out an eye. The neck is protected by a heavy leather collar also cinched very tight. Upper body is protected by thick leather and sometimes chain mail over that. Striking arm is protected by thick leather padding.

The top of the head and the cheeks are left unprotected - these are the target zones.

There is no lunging around. Opponents stand one blade length from each other and only the striking arm is allowed to move. You cannot move your upper body or head at all. The worst thing you can do is to try and duck a blow - you're automatically disqualified if you do that. It's not good.

Getting hit doesn't hurt. Getting sewed up without anesthetic does. Forget painkillers since they would make you too slow. You aren't even supposed to drink 24 hours before the duel and if you get solidly hit, you'll only be allowed a couple of cold ones after the duel.

"most often and counter intuitively the left side…"

Actually, think about that for a moment; it makes perfect sense - a right-handed opponent will strike most of their horizontal blows to their opponent's left side. A wound on the right side is normally the result of two lefties duelling.

"how would a tourist go about arranging an authentic duelling scar…"

You just can't. And three months would be way too fast even for a member of a duelling Verbindung - in Freiburg people would practice for most of the year before their basic duel, and then would work a couple more months on horizontal strikes before being pronounced ready for an advanced duel (I gained some notoriety back then as the only American who had fought two duels as well as the fastest time between basic and advanced - 2 weeks)

And remember, not every duel results in a scar!

(Although I suppose you could pay someone to hit you in the face with a duelling blade)

Ironicamente, esta Italian documentary film from the sixties is still the best I've found. Skip ahead to 2:30 for the duel portion.

I am not a member of such fraternities, but my father was and my brother is, so I have some good second-hand knowledge of these traditions.

Such duels are always between two fraternities, so to take part in one you would first have to join one. Eligibility criteria differ from fraternity to fraternity, but practically all require that you are a student of a local university. Most (but not all) are very patriotic and often require that you are a German citizen (or at least a citizen of a German-speaking country). Some even require that you are a citizen by birth and will not accept naturalized citizens (which isn't uncontroversial even in the fraternity community).

Also, before you are ready for a duel, you will have to train regularly for several months. Going into a duel without proper training would be dangerous for you and shameful for your fraternity.

So as a tourist, you can pretty much forget about participating.

Are there other precautions a tourist duellist should take note of (e.g., applying local aesthetic prior to the event or stocking up on pain killers or getting one's clothes cleaned afterwards or what to wear)?

Not being afraid of the pain is part of the challenge (literally: Duelists are evaluated by their own fraternity after the duel, and it is usually considered more important to fight bravely than to fight successfully), so taking a painkiller before a duel would be against the spirit. It would also be a very bad idea because painkillers affect reaction and coordination, so taking them would be a huge handicap and likely lead to far worse injuries.

I was also told that the wounds one takes during a duel don't hurt at all at first due to the shock and high adrenalin levels. The doctor who is sempre present during these duels often stiches the wound immediately before the shock wears off, so a local anesthetic isn't even required. According to my father he only saw a doctor apply a local anesthesia once, and that was because it was a very unusual and complicated cut which took far longer to stitch than usual.

People wear protection clothing during the duel which protects the whole body up to the chin (plus goggles which protect the eyes and ears) which are usually owned by the fraternity, so whatever one wears under it is also protected from blood.

I'm not sure if you're aware, but these fraternities and their traditions are met with derision or disgust by a great majority in modern German society.

Besides that, these duels are usually carried out inside the fraternity houses. I'm surprised, but take your word for it, that some of them are open to the public. Anyway, they probably aren't attracting a lot of spectators. You seem to have in mind a big festival like a Knights tournament. It's definitely not like that.

I don't know if there are any exceptions, but the fencing is done by the members of the fraternity. To join you would have to be a student (usually at a university in the same city). I suspect that letting tourists participate would be so much against the spirit of these societies that you couldn't consider it authentic anyway.

De acordo com a https://de.wikipedia.org/wiki/Mensur_(Studentenverbindung), the duels have the same legal status as boxing fights, so as long as there are safety precautions and the participants know what they're getting into, there shouldn't be a problem. I see no reasons why this should be different for foreigners.

No fraternity would allow what you want. Your wish seems to me more boyish than masculine.

Like in dangerous sports like archery: The first what a responsible person would do, if others seem to not taking things serious enough, is to stop them to participate.

Just to rectify some things: I am a member of a Corps (political neutral and other nationalities welcome) which is a "fighting" fraternity. True is:

• Dueling is not only illegal, but also morally considered as bad by the vast majority of us members of "schlagende Verbindungen". There is only a quite small group practising it.

• What we still do as a tradition, is the "Mensur" ("Bestimmungsmensur" where you are not allowed to chose your opponent to avoid duels for example), mostly as a prove of commitment to the fraternity: It is "fighting" with sharp blades, but with a number of important rules to minimize injuries, some of them imply for example, that only opponents of same size, speed and skill are allowed to fight each other, more harsh rules apply to distance, stance, technique, and so on.

• It is a good habit to get acquainted to your former opponent (always from another fraternity) after the fight, to even get friends, and least exchange a silver plate (or similar) as a reminder on that.

• For me, I have seen strong advantages for the cohesion of the fraternity because of this. But I am not fanatic in this point, I see the disadvantages too. For me it was never a main point, but this differs for others. True is, there is a difference between fraternities who "fight" and others in cohesion and team spirit, this is the main point in my eyes, why we continue with that, besides tradition.

• For me, but everybody sees it in their own way, a scar shows no proof of being a man, more of being a bad or at least careless fighter.

• Fraternities are often critized as mentioned above. One point is, there are as many types of fraternities as political parties, some are very right-wing, that's not false, and there are not few who love excessive drinking, but that can happen in the twenties... At least one cannot judge all fraternities at once. We have had also teetotallers, conscientious objectors, and others as members- both not the majority, clearly :-)

One thing mentioned above is definetely untrue: "steep hierarchies.." I don't see that. There is an initiation phase where you have to work more, this is true, but the "leaders" and positions are changing every semester, every member has the chance and is expected to accept duties and charges, after some time. In the opposite, German fraternities have a long (often > 150 years) democratic tradition, this was one reason of their existence, and there are some similarities to a parliament process in the fraternity life. Fraternities were forbidden by the Nazis for example.

The dueling scar may be considered a mark of honor by the fraternities that still practice dueling, but outside that small group a dueling scar is meaningless at best and may mark you as a fool if the story of how you got it becomes known.

Duelo was somewhat accepted several centuries ago, but is against the law just about everywhere these days. Society no longer accepts dueling as a civilized way to settle disputes, so a dueling mark is no longer a mark of honor.

By the 1770s the practice of dueling was increasingly coming under attack from many sections of enlightened society, as a violent relic of Europe's medieval past unsuited for modern life. As England began to industrialize and benefit from urban planning and more effective police forces, the culture of street violence in general began to slowly wane. The growing middle class maintained their reputation with recourse to either bringing charges of libel, or to the fast-growing print media of the early nineteenth century, where they could defend their honour and resolve conflicts through correspondence in newspapers.

Finally, duels were about restoring honor to a person who had been slighted in some way. Going into a duel without that precondition makes the duel non-authentic and therefore pointless.

I started a very similar society at Cardiff University during the early 199os,we were all members of the Officers Training Corp , and were based loosely on German Corps rules . As a result now have a scar across forehead (20 stitches) and left cheek (10 stitches), the hardest part was sourcing the swords and other equipment from Germany.
