Like Victor Tausk, Herbert Silberer (February 28, 1882 – January 12, 1923) was yet another admirer and victim of psychoanalysis, although, unlike Tausk, Silberer wasn't a medicine doctor but a layman. On the other hand, just like Tausk, at least at first, Silberer was inexplicably attracted to Freud, like a moth is attracted to a candle, unaware that it will be burned to death if it gets too close to its flame.
Unlike most of Freud's followers, Silberer wasn't Jewish. Both Tausk and Silberer had things in common both in life and death.
On January 12, 1923, Silberer, like Tausk, allegedly committed suicide, under similarly suspicious circumstances.
As time went by, both of them were in opposition to Freud, and both were rejected by him. Both were much younger than Freud, and talented. Both were Christians (Tausk was a convert). And both died hanged on a cross window, a rather symbolic death. A case in point: Freud was a rabid hater of all religion, and Christianity in particular.

This is a brief tale of Silberer’s fateful relationship with Freud.
In June 1909, Silberer sent Freud an essay that appealed to Freud. This is how, in a letter to Jung, of July 19, 1909, Freud described his newest acquisition:
Silberer is an unknown young man, probably a better-class degenerate; his father is a well-known figure in Vienna, a member of the city council and an ‘operator’. But his piece is good. (1)
N.B. Freud himself was a degenerate, but not of better-class.)
A year later, Freud met Silberer for the first time in July of 1910, and in October the “outsider” formally joined the Vienna Psychoanalytic Society. (2)

A convinced Christian

Freud wasn't wholly taken with his new disciple. As he wrote the Swiss psychiatrist, Ludwig Binswanger, on April 12, 1912, he felt that Silberer, is not part of the Vienna group at all, significantly adding that, He is a convinced Christian (3), in Freud’s opinion not a positive thing, since the deranged Freud viewed Christianity as his mortal enemy.

A short bromance

In 1914, Silberer published his contribution, to Freud’s Interpretation of Dreams., initially welcomed by Freud, although it was only a matter of time before he became critical of his talented disciple.
On April 28, 1915, only a year later, Silberer, for the last time, attended the meetings of the Vienna Psychoanalytic Society. Subsequently, in 1919. and, again, two years later, in 1921, Freud rejected Silberer’s ideas. (4)
This didn't bode good for Silberer's well-being..

Don't try to contact me

As Roazen revealed, on April 17, 1922, Freud sent Silberer a note telling him, in no uncertain terms, that their relationship had ended, writing:
I request that you do not make the intended visit with me. As the result of the observation and impressions of recent years I no longer desire personal contact with you. (5)
That was a brief, but definitive, dismissal, but was it a reason enough to commit suicide? After all, Silberer's relations with Freud weren't exactly friendly for quite a while. Nonetheless, nine months later, Silberer was dead, allegedly by his own hand.

One reason for Freud’s rejection of Silberer may have been the latter’s continued relationship with the Freudian defector, Wilhelm Stekel, as well as Silberer's editorship of a competing magazine, Psyche and Eros. (1)

In a deep rage

Silberer’s actions, weren’t helping his relationship with Freud. In particular, when Silberer invited other psychoanalysts to contribute to the journal, as it’s been alleged, Freud, for once, was seen, in a deep rage, growing pale. This didn't bode good for Silberer. And Freud had a long memory.
Unsurprisingly, as a result of their enmity, ten years after Silberer joined his psychoanalytical circle, Freud formally ejected Silberer from psychoanalysis.

Suicide was no surprise

Absurdly, as if people expected Silberer to kill himself, Roazen claimed that Silberer's suicide was no surprise. (2)
This is a false claim since Silberer’s death was a shock to all who knew him which is apparent from Helene Deutsch's husband's letter to her in which he informed her that, Among the psychoanalytic members there is a rather subdued mood on account of Silberer’s suicide. (3) Why would there be a subdued mood, if Silberer's suicide wasn't a suprise?
            Also, another of Freud's unruly disciples, Stekel pointed out that Silberer’s suicide was unexplainable. No one, neither family, nor his friends, nor acquaintances had an inkling that he was suicidal.

Lively for one week only

Only a week earlier, Silberer delivered an acclaimed lecture. As Stekel recalled, on this occasion, he had never seen Silberer so lively and engagingly charming. (4)
And yet in a week, Silberer was dead, allegedly by his own hand, in a most bizarre fashion.
Apparently, contrary to Roazen’s claim, Silberer’s death wasn’t expected, and one can only wonder what prompted Roazen to make such a bizarre claim. Possibly, one can explain this kind of blatant cover-up by the violent reaction of the psychoanalytical mafia to Roazen’s account of Tausk’s alleged suicide in 1969.
Accusing Freud, of murdering one of his disciples, was bad enough, accusing him of murdering another, was unforgivable. Thus, not having much civil courage to spare, and he wasn't the only one, Roazen participated in the at least, half-a-century-long cover-up of Freud’s murderous orgy.

Freud didn’t acknowledge Silberer’s suicide. Only, An anonymous one-paragraph obituary was published in the Bulletin of the International Psycho-Analytical Association in 1923. (1)
A year later, Silberer’s friend, Stekel, wrote Silberer’s obituary stating that once Silberer accepted the position of editorial assistant in the new analytical journal, Psyche and Eros, Freud was finished with Silberer. (2)

Demonic forces

As Stekel explained Silberer knew there was, a deep, unbridgeable chasm between himself and his beloved and revered teacher. (2)
So, even though Silberer loved, and revered, Freud, the latter had no love for his former disciple. Notably, referring to Silberer's state of mind, Stekel wrote, I have no idea what demonic forces hid beneath his serene exterior. (3) But what if those demonic forces hid not in the serene Silberer, but in the insane Freud?
As Schur recounted in his Freud's biography, talking about himself, Freud claimed that, a human being's demon is the best part of him. And, as Schur pointed out, In later years he (Freud) would often speak of his inner demon. (4)
As Stekel believed, not only Silberer's death may have been the result of his involvement with psychoanalysis.
Silberer shared the fate of many gifted people, he wrote, who concerned themselves with analysis without being thoroughly analyzed. (I refer only to the brilliant Viennese researchers Schroetter and Tausk, who also committed suicide, he explained.) (5)
So, all of them committed suicide because they weren’t analysed enough? A case in point: Freud wasn't analysed at all, and yet he didn't commit suicide.
N.B.  As Freud claimed he himself was psychoanalysis, and if we accept his claim, then Stekel's quote becomes even more ominous.  Hence, it was the fate of people who concerned themselves with Freud that were dying.
Not unexpectedly, Jones ridiculed the legendary “dangers of psychoanalysis; [the claims that] it either drove people mad or sent them to their death." (6)
Thus, if we believe  Jones, we should look elsewhere for the cause of Silberer's demise.  Although, it is doubtful that Jones knew about Freud's murderous nature.

Don't be fooled by Freud's intellectual looks, including his glasses. A large and scary number of serial killers including Jeffrey Dahmer, Dennis Nilsen [The British Dahmer], Harold Shipman [Dr Death), Dennis Rader [BTK killer], Gary Ridgway [Green River Killer] just to name a few, were wearing glasses.
Serial killers, Even though they’re monsters, they don’t look or act like monsters ... What makes them monsters is ... that they “don’t lose any sleep” over what they do.
What about Freud being a compulsive writer? He wouldn't be the only criminal suffering from a mental condition called hypergraphia.
Also, Dennis Rader, the BTK killer, was a compulsive writer keeping a diary. Another Dennis, Nilsen, suffered from the same affliction. There were many others.

According to Roazen, Silberer killed himself in a horrible way nine months later; he hanged himself on a set of window bars, leaving a flashlight shining in his face as he strangled so his wife could see him when she came home. (1)
Unfortunately, Roazen didn't specify where this information originated. Without doubt, Silberer died a horrible death, but whether it was a suicide is doubtful.
Rather, considering the staged character of his death, and its uncanny similarity to Tausk's alleged suicide, his death appears, once again, as in Tausk’s case, to have been a case of a staged murder rather than of a suicide.
Moreover, Roazen's claim that Silberer hanged himself on a set of window bars cannot be true. Since Silberer didn't live on the ground floor of his house, there wouldn't have been any bars on the windows.
[The Annahof building, where Silberer lived and died, was rebuilt in 1894. housing on the ground floor the Tabarin theater. (2)]
Silberer’s was not a "normal" suicide by hanging. Considering that the windows in general are only 90 cm above ground, hanging oneself on window bars, assuming there were any, is not an easy task.
In fact, the claim that Silberer hanged himself with a flashlight shining is his face is absurd. As a matter of course, there was no way for Silberer to adjust the flashlight before the suicide so that it would shine on his face once he hanged himself This must have been done after his death, and, thus, by his murderer.
In this way, by this ritualised procedure, the murderer was leaving his highly symbolic signature. Without a doubt, Silberer's suicide appears to be a textbook case of a staged suicide.
Also, the fact that Silberer was hanging so that the wife would have seen him is yet another clue that this was a murder rather than suicide. Even assuming that he killed himself, what would be the reason to scare his wife in this bizarre way?

This is what one of Freud’s female followers, the psychoanalyst, Helene Deutsch, herself analysed by Freud, had to say about Silberer’s fate.
Herbert Silberer, a long-standing member of the Vienna society... no longer on good personal terms with Freud, killed himself.

Mental overstimulation (like Tausk)

As Helene's husband, Felix, informed her, Silberer put an end to his life by means of the rope - allegedly on account of “mental overstimulation”.
Apparently, Felix was not convinced about the alleged cause of Silberer's death, although it is unlikely that he was making a connection between Freud’s personal aversion to Silberer, and the latter’s untimely death.
Silberer's suicide wasn't the only one at the time. As Felix recounted, among the doctors there has been yet another suicide.

Dr Kahane's suicide

Dr. Kahane, the electrotherapist, who once also belonged to the society, slit his Radialis - supposedly because of neediness. I knew him well - an elderly rather eccentric gentleman.
Significantly Felix added, I’m curious as to how Prof [Freud], takes these things. * With glee, of course.
Thus, under Freud's watch, several of Freud's disciples committed a suicide: Tausk, and Silberer, Max Kahane, to name a few.
Remarkably, Kahane, yet another of Freud's opponents, died on January 11, 1923, a day earlier than Silberer.
As Roazen pointed out, Freud's dismissal of Silberer was curt and official, in a discrete footnote, "bravely" revealing that in his view,

Controversies or suspicious deaths?

No doubt there are still some unknown controversies in Freud’s life. Wittels (Freud's earliest biographer) mentioned, for example, Freud having severed relations with Max Kahane. **
Apparently, Freud was spring-cleaning the house.
