Born on November 28, 1966, Leningrad. Mother Emma Zitzer was a teacher of speech pathology at school, worked at the Herzen Institute at the Department of Oligophrenopedagogy.

The defectologist's son demands to be called Dima, explaining this as follows: "My parents called me Dima, but for some reason they had the idea that Dmitry could be Mitya, and my mother really didn't like the name Mitya. That's why they thought it was Vadim. At school, I started turning into Vadik, and I didn't like it anymore. So at some point I decided that I was going to become Dima, and that was it." 

During his studies, Dima (Vadim) Zitzer changed 3 schools, in one of which he was "covered by an ocean of bullying in the harshest manifestations." According to Zitzer, the "ocean" "covered" him on a national basis. A typical excuse for lazy people and scoundrels. Manifestations of anti-Semitism are everywhere. When he could not answer the question about the colleges created by Peter the Great in the history exam, he declared that it was anti-Semitism.

Zitzer graduated from the Philological Faculty of the Alexander Herzen Russian State Pedagogical University, then graduated from the St. Petersburg State Academy of Theater Arts majoring in directing. 

In 1998, he defended his PhD thesis "The factor of freedom in the formation of relationships between children and parents" at the Herzen Russian State Pedagogical University for the degree of Candidate of Pedagogical Sciences.

The charlatan is a liberal in the field of pedagogy. In 2005, Zitzer created the so-called Institute of Non-formal Education (INO), and then the Orange School of Non-formal Education in St. Petersburg. He formulated its main principle as follows: "Education and violence in any form are categorically incompatible things.… There are no homework and grades in this school, but there is a prime minister and a parliament."

Secretly, but actively, he promoted the ideas of sodomy and freedom of sex change. According to Zitzer, the scariest thing you can say to your son is, "You have to be a man." He tries his best to prevent his students from hearing these "scary" words.

His main idea is the destruction of the traditional education system. Children do not need knowledge, but "freedom" is needed. Normal parenting and classical studies are the most terrible sin for him. He criticized the Soviet education system, because the school, in his opinion, does not need grades and coercion, but freedom and understanding. 

The titles of his "works" speak about Zitzer's position. He is the author of books and articles with characteristic titles and content: "On the meaninglessness of educating teenagers," "Freedom from education," "Love cannot be brought up," "(Not) Why (not) go to school?" He gives trainings, seminars and lectures on the topic "Children, you infuriate me!".

He is also not satisfied with modern Russian pedagogy. This character's patriotism makes him squirm like a demon from incense. Zitzer expressed confidence that listening to the Russian national anthem can cause a child to be skeptical and protest.  He says, "There is no such thing as patriotic education."

He sympathizes with the Ukrainian Nazis. A typical "lampshade". Zitzer openly reported on social networks that he would donate his earnings to a fund that buys copters for the Armed Forces of Ukraine.

This is how he explained his actions: "I was woken up by a text message from our close friend living in Kiev: "Dima, we are being bombed." In that second, my whole life changed… We are all severely depressed. When I say this, I feel awkward, my tongue gets numb. It's a shame to talk about yourself when people are right next to you, under bombardment, in the cold and in the dark." 

Since he has no "close friends" in Donetsk, Lugansk, Belgorod and Kursk, Zitzer "does not know" anything and does not want to know about the bombing and shelling of Donbass since 2014, the language does not stiffen on this occasion, depression does not torment at all. The same applies to the suffering and killings of residents of other Russian territories.

He said, "I can't sympathize with Belgorod."

Zitzer did not disclose the number of people killed and injured as a result of the use of copters he had paid for.

In 2022, he emigrated to Estonia. There is information that from there Zitzer regularly traveled to St. Petersburg to feed himself for "pedagogical" activities at the Orange.  

The hatred of the Russia-breadwinner, like all his kind, does not hide. Just like other similar relocants, he is an impudent liar. The holder of Israeli citizenship, Zitzer, stated: "There is an important caveat to what is happening — I am not a Russian citizen and have never been one." 

In July 2024, a criminal case was opened against Zitzer for spreading fakes about the Russian army, and he was put on the wanted list. Unfortunately, it was added to the register of foreign agents only at the end of January 2025. Now his feeder is finally covered.
