sans serif

Looking for a sans-serif with strongly different stroke weights

It seems to me that it's hard to find a sans-serif typeface that has anything other than identical or nearly-identical stroke weights throughout. I'm looking for something much more like a Didone, or at least a Garalde, in terms of stroke weight, but a sans-serif. Has anybody got any recommendations? Thanks!

Identifying Two Sans Serifs

Hi All.

I'm new to Typophile and trying to get a feel for how all this works. Sorry, in advance, if I'm out of line.

Got two typefaces in the attached images. Would love to know what they are.

DUNDERDON looks pretty close to Helvetica, but the R is different.

ADAM KIMMEL, I'm totally unsure.

Thanks for the help. Super grateful.
