[2] In spring 1870, Belling was a pupil of Danish theatre director Frederik Adolph Cetti in Bergen.
She made her debut in the lead and only role in Johan Ludvig Heiberg's vaudeville monologue Emilies Hjertebanken, which was successfully received.
In Dagbladet, it was reported that "the biggest event of the evening, however, was Miss Belling in Emilie's Palpitations, a debutante of the first rank.
The way in which she already knows how to fill this demanding little role, the joy, freshness, life that burst out of all the lines, brought the audience into the best mood, and with strong and general shouts of bravado she was evoked.
Like all our talented actresses, she is a Bergen woman, and in her our stage has probably found an artist who wants to assert the reputation of her native town".
