 Gramm is often referred to as "Mimine", Salzedo's pet name for her.After resigning from his position at the opera in 1913, Salzedo formed the "Trio de Lutèce" with Georges Barrère on flute and Paul Kéfer on cello, which toured extensively in the United States.The trio was scheduled to play in England, so Salzedo and Mimine took the opportunity to honeymoon in Europe; in England, they were introduced to various members of the nobility, and at one point, Salzedo performed for the Princess of Battenberg.
