What a great first post!!! Welcome to the forum. Thank you for sharing your information.I know that this is an old thread - but I wanted to provide a bit more information on J.D. Heise, who was my great great uncle. John Dietrich Heise (originally Johan) was born in Bremen, Germany, in 1865 and emigrated to San Francisco in the 1880s. He opened a grocery shop and liquor distribution business around 1903. Their first location was at the SW corner of Valencia and 16th Streets. In 1906 he bought a property at the corner of 16th Street and Rondel Place (3079-3083 16th Street - near Valencia). [Note that the street numbers on 16th Street range from the low hundreds near the Bay to the East, up to about 3800 in the hills above the Castro to the West.] On this property he built a three story building in 1907. He moved his liquor business here and also opened up a boarding house and a "Cafe" (i.e. bar). He operated the liquor business from this location until prohibition when he sold it. In 1976, the top two stories of this building burned down but the ground floor was saved. For many years after J.D. sold it, it was a place called Esta Noche, a legendary gay and transsexual bar that primarily served the growing Latinx community in the Mission district. This is now the location of the Bond Bar. After selling his liquor business, J.D. became head of the nursing program at the Franklin Hospital. He died in 1943. Attached is a brief article about J.D. Heise and Co. from a 1910 edition of a magazine called "Organized Labor". As a side note, J.D. was also a "Captain" in the San Francisco Schuetzen Verein, a German protection society and social club. He was a expert marksman and traveled around the world to participate in shooting matches.
