The original Maubert Avenue was laid out by 1901 and ran all the way to Los Feliz Blvd. That road was rebranded Hillhurst in 1914, so the Maubert moniker was revived for this little street two years later. I found only one likely source for the name: Place Maubert, a small square in Paris’s Latin Quarter. “Maubert” itself is a corruption either of d’Aubert, a 12th century clergyman at the long-gone Saint Geneviève Abbey, or Maître Albert, a theologian who taught there in the 13th century. (Rue Maître Albert does connect to Place Maubert.) Place Maubert was considered a slum in the early 20th century – an unlikely inspiration for a brand new Los Angeles street. I don’t know who could have picked it.
