Charlotte Braun - Miss Othmar

Miss Othmar served as Linus's teacher starting in 1959. There was a series of comics where Linus had to bring egg shells to class so she could teach the class about igloos but Linus kept forgetting to bring the shells. As with most adults in the strip, Miss Othmar was never seen. In the strip she is never heard either though the children have conversations with her. She was given an unintelligible speaking voice in TV specials in the form of trombone sounding "wah-wahs". This became her trademark and all other voices of adult characters off camera in the cartoons and is sometimes parodied in other programs.

Linus developed a long-lasting crush on her. As a result, Linus held her in unreasonable esteem, which made his discovery that she earned a salary for her profession a crushing disillusionment he tried to rationalize away. Though infatuated with her, Linus understand that she can't really love him,he's content with just being "fond of the ground on which she walks."

Eventually, Miss Othmar married, assuming her married name of Mrs. Hagemeyer; Linus, however, continued to call her Miss Othmar, and other characters in the strip began referring to her as Miss Othmar again as well. (As Linus said, "In real life she's still Miss Othmar!")

Although Miss Othmar quit teaching after she got engaged, she returned to teaching a few years later, much to Linus' delight. However, in 1969, Miss Othmar was fired following a teacher's strike, and Linus was devastated. Miss Othmar's replacement was Miss Halverson ("Halverson" being the maiden name of Charles M. Schulz's first wife, Joyce), whom Linus initially refused to accept as his new teacher, although he eventually seemed to learn to live with it.

Miss Othmar talks briefly to Sally in the TV special You're Not Elected, Charlie Brown.

Marcie mentions that she is taking organ lessons from a "Mrs. Hagemeyer" in a 1979 strip, but it is unclear whether this Mrs. Hagemeyer and Miss Othmar are one and the same.
