I've been making notes for myself about character's ages as I've been going through Twin Peaks materials.

Albert Rosenfield's age seems to have escaped me. Anybody know his age? The closest indication I've seemed to come to is a Wikipedia article indicating he was 21 as of 1977, as determined by Cooper's audiotapes. Can anybody verify this? Thanks.

According to Twin Peaks cards (I think) he was born 13.09.1956. So it makes him 33 in 1989 and yeah, 21 in 1977.

I wonder if he was able to finish his education (including medical school and FBI academy) by 21? Is it possible in USA (I'm not an american education system expert)?

Or  was he like Sheldon Cooper from The Big Bang Theory? (Which is probably true)

Thanks so much for the info! Very much appreciated.  

Re: realism regarding his age and career/schooling: absolutely not, which is why I stick my fingers in my ears when I hear about the exact nature of his schooling/work career. I'll just go with the fact he was born in 1956, and ditch everything else.

 It may sound like I'm being hopelessly finicky, but there are some things you can't just mess around with. For instance, the minimum age entrance to be in the FBI is 23-- I should know, because it's been a career option I've been pursuing for after my stint in my military. This isn't a new age limit, it's been around for a long time.

 Plus, you aren't automatically made an agent with full working rights and the like. A Marine Lt. I knew told me that some of his friends had tried to go the FBI agent route straight after college, and wound up doing stuff like fetching coffee and paperwork. And even after that, you'd get assigned to a senior partner, and take about a year hanging around with them.

As for being a forensic pathologist, going by what the scripts put him down as. Albert would need to have the schooling of a medical doctor, with the specialization of working in forensic medicine. So that means, if he followed the normal timeline for earning a medical degree, he would be about 28 at graduation. I have various friends who are doctors or are studying to be doctors, and despite their intelligence, none of them have the brilliance that various movies/books/TV shows like to try to slap on characters. They all graduated at about 28, as well. 

 Given Albert's consistent characterization-- brilliant, but down to earth and practical-- it strikes me as bizarre to try to shoehorn some kind of prodigal genius backstory that some of the extra material seems to suggest. Then again, I'd rather put it down to ignorance on the part of the authors as to what goes into becoming a doctor/forensic pathologist/FBI agent, than any kind of special sparkly history.

21 is honestly ludicrous, for a variety of reasons.

 So for me, Albert was still extremely ambitious and intelligent, and got recruited into the FBI straight out of med school at 28, and is now about 5 years into working for the FBI.
