The actress who takes on the role of Dr. Elsa Curry from 2018 to 2020 on "Chicago Med" is Brooklyn, New York, native Molly Bernard. A veteran of series like "Transparent," "Alpha House" and "Younger," Bernard portrays Dr. Curry through the show's penultimate 19th episode of Season 5.

As noted above, during her time on "Chicago Med," Elsa eventually finds herself floated as a possible romantic match for Gelhfuss's Dr. Will Halstead. In this regard, toward the conclusion of the "Who Knows What Tomorrow Brings" episode, Elsa is at a crawfish boil party organized by Dr. Crockett Marcel (Dominic Rains) when Will notices that she's looking unhappy. He attempts to be friendly and cheer her up, but Elsa sees his interest as something much more than he intends. Then, in a subsequent installment, Elsa buys concert tickets for two and is about to ask Will out on a date, only to be crushed as she realizes she's misinterpreted his feelings toward her. 

Bernard's final appearance on the series comes in the "Just a River in Egypt" episode of Season 5, after which the character vanishes from the show without further mention. So, while the Elsa Curry storyline does have a momentary high-profile part to play on "Chicago Med," it's understandable that even long-time fans may have trouble putting a name to the actress who plays the intense but ultimately short-lived, love-lorn character.
