FYI to whomever may view this content report:

I've just now attempted genealogically researching Mr. Conrad (whose original name was Conrad Robert Norton Falk), and 1935 does, indeed, appear to be his accurate birth year; there's an abstract accessible online, that reflects the various details appearing on his Chicago, Cook County, Illinois birth certificate, and it indicates that he was born on 1 March 1935, and that the birth was officially registered on 11 March 1935. His mother, Alice J., is indicated to have been 17 years old at the time. His father, Leonard H., was 20.

It looks like at one time Wikipedia was indicating that Robert Conrad's birth year was in question, though, since then, Wikipedia is indicating 1935 birth year (as, likewise, does IMDb).

Incidentally, Wikipedia presently states that Robert Conrad's mother was 15, and his father 16, when he was born. Those ages may well be correct: I've been a genealogist for over 30 years and can attest that it's very commonplace, in old records, of in particular prior to the 1950s, for ages to have been inaccurately stated, especially when young people were involved, wanting to seem older.

I've made revisions and additions to Mr. Conrad's TMDb profile page, since I'm fully comfortable with the reliability of the details I've found. I've also updated the TMDb bio text to reflect what Wikipedia's article about Mr. Conrad now states. (I've, meanwhile, confirmed that he, indeed, is still doing the weekly 2-hours radio show, that the bio mentions.)

It may be a good idea to lock the revised bio and birth year, so they won't wind up changed back to stating that he was born in 1929.
