can you list the top 10 documented people who had perfect recall and recalled in detail their memories from decades before or who could not forget anything




Scientifically, the condition characterized by the inability to forget is known as **Highly Superior Autobiographical Memory (HSAM)**, also called **Hyperthymesia**. People with HSAM can remember almost every day of their lives in vivid detail, particularly personal events.

It is important to distinguish between "eidetic memory" (photographic memory, which is often visual) and HSAM (which is autobiographical). To date, there is no scientific evidence of a human who can recall *every* piece of information they have ever processed (like a video recorder), but those with HSAM come the closest.



Here are 10 of the most notable, documented cases of people with extraordinary memory capabilities:



### 1. Jill Price
The first person ever diagnosed with HSAM. Her case, documented extensively by neurobiologist James McGaugh at UC Irvine in 2006, launched the modern scientific study of the condition. She describes her memory as a "running movie that never stops." She can tell you what day of the week a specific date fell on and what she was doing that day, dating back to 1980.



### 2. AJ (Pseudonym for Jill Price)
While Jill Price is her real name, she was originally referred to as "AJ" in scientific journals. She is the baseline for all subsequent research into the condition. Her memory is involuntary; she does not "try" to remember, she simply cannot "stop" remembering.



### 3. Nima Veiseh
Veiseh is one of the most famous cases of an adult who developed HSAM. He discovered his ability after finding he could recall the specific details of a day 15 years prior—including the exact color of a shirt a person was wearing—with perfect accuracy. He often uses his memory to track his life in "chapters."

### 4. Rebecca Sharrock
An Australian woman famously known for having "Total Recall." Sharrock can recite the entire *Harry Potter* series word-for-word from memory. She has documented her childhood memories from as early as 12 days old, recalling the sensation of being placed in a car seat—a claim that has fascinated memory researchers.



### 5. Brad Williams
Known as "The Human Google," Williams has the ability to recall news events, sports scores, and personal experiences from almost any day in his life. He was featured in the documentary *Unforgettable*, which showcased his ability to answer trivia questions about specific dates with pinpoint accuracy.



### 6. Bob Petrella
A television producer who has been verified by researchers to have HSAM. He is exceptionally skilled at recalling the specific weather, news headlines, and personal interactions he had on any given day for the past several decades.



### 7. Joey DeGrandis
DeGrandis realized he was different when he noticed he could remember specific details about his childhood that his peers had long forgotten. He was part of the original study group at UC Irvine and has been tested extensively to ensure his memories are not "reconstructed" fantasies, but accurate snapshots of the past.



### 8. Solomon Shereshevsky ("S")
Unlike the modern HSAM cases, "S" was studied by the famous Russian neuropsychologist Alexander Luria in the early 20th century. He did not have autobiographical memory; he had a **synesthetic memory**. He could memorize endless lists of numbers or poetry and recall them perfectly years later. However, he struggled to *forget* information, which Luria noted made "S" unable to comprehend metaphors or abstract concepts because he was too focused on the literal, detailed imagery of the words.



### 9. Rick Barron
Barron is one of the few individuals documented whose HSAM allows him to recall not just personal dates, but also a massive amount of historical and public information. He has been cited in research as having a "near-total" ability to link personal autobiography with public events, creating a dual-timeline of his life and the world.



### 10. Louise Owen
One of the earlier cases identified by the UC Irvine team. When researchers tested her, they would throw random calendar dates at her from decades prior. She would consistently identify the day of the week, the weather, and what she was doing. Researchers verified her memories by cross-referencing her journals and diaries from those years.

### Important Note on these cases:
* **The Burden of Memory:** Almost all individuals with HSAM report that it is not necessarily a "superpower." Because they cannot filter out unimportant information, they are often prone to obsessive-compulsive traits and find it difficult to move past traumas, as they can remember hurtful events as clearly as they did the moment they happened.


* **The "Movie" Analogy:** Most of these people state their memories are not "files" they look up, but rather associative: mentioning a date triggers a "playback" of the sensory input they experienced on that day.


* **Scientific Validation:** Researchers use "blind" testing to verify these individuals, often using public databases (like the *New York Times* archive) to verify if the minor details they remember (the weather, a specific news event) actually occurred on the day they claim.
