Daniel McCartney

Managing Real Estate Broker with Fathom Realty PB00068179

Daniel McCartney was born in Westmoreland County, Pennsylvania back in 1817. I don’t have a lot about his childhood however, what I can tell you is he was legally blind living with relatives for his entire lifetime, he never married.

He died in 1887 at 70 in Wilton, Iowa. So not an eventful life you may say or be asking yourself. However, as you all know there is a reason I’m writing about him today and now you’ll know why. You see back then he was a walking, talking calculator of tremendous knowledge. He suffered from a (if you want to call it that) disability called Hyperthymestic Syndrome. Don’t know what that means? Well you’re in luck for here we go.

He was famous for his mental ability in two specific areas. He could recall every single day in his life from the age of nine until his death. You could give me a date and he could recall the weather conditions, what he did during the day and what he ate. He also could recall local, regional and national events on any given day. His other ability was to compute difficult mathematical equations within a matter of seconds or in a minute or two. He was once asked to provide the cube root of 4,741,632, without anything other than his mind he was able to compute the answer in three minutes. For those of you who like math the answer is (-168); and 389.017. After you get past two plus two I start to panic.

As I’m writing this there are only about 25 people in the world with this capability.

I have a hard time remembering 15 minutes ago. This is a remarkable ability but one I am glad I don't possess. Some events are worth forgetting about.

Hi James Dray - Marilu Henner (Taxi) has this ability - hyperthymesia. She can recall everyday of her life. Her earliest memory is of her Baptism. I find this fascinating! Thanks for sharing Daniel McCartney's story.

Hello James

That is quite amazing and being blind and able to do this is incredible. Without seeing dates, numbers, etc and to be able to quote and or remember, wow!

Good morning again James. The first ability is one that a current star has. I can't recall her name though.

Great story.  Our first CPA could add rows in his head and always come up with the right answer.  He was famous in his own right.  One of his daughters was chosen to be a Bond girl when Sean Connery ruled 007.  A

James- needless to say, I do not suffer or have this syndrome.  I do well to remember what I did yesterday.

What an amazing ability. I went to school with a kid that could do extreme math in his head. He had some form of autism. BTW...I grew up near Wilton, IA.

Oh my, I certainly don't have this problem. I forgot my cell phone number this very afternoon! Not like I call myself, but it was embarrassing to say the least!

Like a couple of others here, I recall Marilu Henner as having this ability, which I've seen tested on a couple of interviews with her.  I'm not sure I'd want to remember every day with that much detail but it would be nice to have more memories of more days in my life!
