London, a symbolic name of the 19th century.

The name represents a city, but in a sense it represents a country, an empire on which the sun never sets on colonies almost all over the world. In this era, London represents the world's first power, the unparalleled invincible armada, and the will of the incomparable!

Two days later, Johann and Hans arrived in London.

After visiting Hyde Park and meeting Big Ben, John and Hans spent three days briefly walking around London, feeling the world's first city while secretly being deeply shocked by the power of Britain. In comparison, although the exhibition in New York is like riding a rocket, it is not a little worse than the profound London!

Three days later, John Schran arrived at the Royal Society of London.

"Sir, I don't quite understand."

Hans was a little puzzled about John's itinerary today, and couldn't help asking, "What are you doing here?" ”

"Hehe, I just want to see if there's anything I'm interested in."

Answering the butler's questions nonchalantly, John's eyes remained fixed on the signs posted on the walls of the hall. The Royal Society of London is a bit similar to the Academy of Sciences in later generations, and often holds some scientific lectures, and these notices on the wall are the preview of the lectures, and John uses these things to find information that interests him.

"It's a pity ......"

After seeing the end from the beginning, John shook his head in his heart, hesitated for a moment, and then walked over to a staff member not far away.

"Sir, is there anything I can do to help you?"

Seeing John walk in front of him, the staff member took the initiative to ask without waiting for him to speak.

Today, John put on a dress that he had just customized before he came out, although his face was very young, but his decent dress and outstanding temperament gave him great convenience, and no one would be slacking off in this era of paying attention to status and status.

Very politely bowed first, John smiled and asked, "I would like to ask if Mr. Joseph Liszt is working here?" ”

……

On the carriage back to the hotel, Hans asked with a puzzled expression: "Sir, can you ask what kind of man this Mr. Liszt is?" All I know now is that he is a surgeon, but ...... How did you know about him? Why do you have to go to see his surgical demonstration? ”

Hans really couldn't figure out what John was thinking.

Medicine in this era is really very backward, whether it is the frequent outbreak of infectious diseases or various diseases in ordinary people, there are really not many things that doctors can do, and the backwardness of surgery makes doctors not treated by ordinary people. This is an era when many people still call surgeons physiophysicians, and patients will only choose to let doctors use the knife on themselves when they have to, because that means they will be in very high danger!

So Hans couldn't understand why Johann was interested in such a surgeon, let alone going to see a surgical demonstration that looked like a slaughterhouse!

"Haha, this is a very great surgeon."

John was very excited: "I read an article in a magazine, written by this professor of Liszt, who came up with a very groundbreaking idea...... Well, Mr. Elber, you just need to know that I'm interested in his research. ”

"However, our itinerary ......"

Despite what John said, there was still a hint of embarrassment on the butler's face.

The staff member in the hall of the Royal Society made it clear that Professor Liszt did not work in the building, and he did not usually come to the building, but there would be a public demonstration of the operation on Saturday, and if you were interested, you could go and see it. And looking at John's excited expression at that time, Hans had already guessed his thoughts, and he must have stayed to watch this operation before leaving!

That is, they will be in London for at least four more days!

The four-day delay in seeing a surgeon use a knife on a patient and pull a saw was an incredible thing for Hans! And he didn't understand why the young master of the Huntelaar family was suddenly so interested in medicine, and at this moment he suddenly had a very bad premonition, it seemed that ...... John came to London for this Liszt professor!

However, John obviously didn't think much about it, and waved his hand casually: "Okay, it's just a few more days in London, Mr. Elber, you can book a ticket for a week's time, and we'll rush to Hamburg as soon as we see this operation, right?" ”

"This ...... All right. ”

After sighing secretly in his heart, Hans nodded helplessly. Even if he vaguely guessed John's thoughts, there was nothing he could do but comfort himself after a few words of simple persuasion: "It's just a week, let him go." ”

At the end of the day, he's just a steward, and it's his duty to follow orders.

After negotiating the arrangements for the rest of the week, Hans fell silent, while Johann watched the streets of London around him with great interest, completely immersed in the excitement of meeting Liszt......

Joseph Liszt, a name known to almost all later surgeons.

As a 19th-century surgeon, Liszt's greatest achievement in his life was not to understand a new procedure or to decipher a disease, in fact the only thing he remembered in history and his greatest achievement was to usher in a new era of preventing infections while performing surgery!

In the 21st century, even ordinary people understand a truth, if people accidentally suffer trauma, they should be disinfected with alcohol or iodophor to prevent wound infection. But more than 100 years ago, even the most specialized surgeons would not have thought of this! In this era, surgeons do not wash their hands or disinfect patients before performing surgery, and operating rooms are often exposed to bacteria. Many surgeons operate on patients in tuxedos, shirtless in hot weather, and some surgeons are even considered to have a lot of surgical experience if they operate on a blood-stained surgical gown!

One can imagine how miserable the surgical patients were at that time!

In fact, there was a Hungarian physician who preceded Liszt who also showed this. The alarmingly high maternal mortality rate in the current hospital in Vienna has been linked to the squalid conditions of the hospital. As a result, he made it mandatory for physicians to wash their hands with bleach before touching them, thus reducing maternal mortality to a very low level.

But unfortunately, the research results of Dr. Semelwes are not accepted by people, and the doctors still adhere to the "natural life theory", believing that the ** of the organism is naturally born, and the infection of patients is like the mosquito that can be produced by sewage, and some doctors believe that it is the "miasma" around the hospital that leads the ** of the patient's body, so most people laugh at Dr. Semelweis's research. In the end, the grief-stricken physician, in order to prove his theory, deliberately cut off his own finger during an autopsy on a woman who died of puerperal fever, and died as a result.

Twenty or thirty years later, Liszt's efforts finally changed this qiē.

Like Dr. Semelwes, Liszt was also puzzled by the infection of patients, and then began to study disinfection after coming into contact with Pasteur's bacterial theory, and through decades of unremitting efforts, more and more surgeons accepted the concept of disinfection, so that the role and status of surgeons were truly improved, and the history of medicine left the glorious name of Liszt!

How could John not go out of his way to meet such a legendary figure?

Thinking of the pleasure, John couldn't help but laugh in a low voice: "When you come to London, you will meet Liszt first, and then you will meet Koch after you arrive in Berlin, and you can go to Paris during the middle vacation to meet Pasteur......"
