  1. San Francisco Directory for 1873, p440, entry for Mohr, Rudolph. Meigg’s Wharf was a rough and ready place; here is a photo of Abe Warner’s Cobweb Palace, a saloon just near the SF Stock Brewery, and another. vv Meigg’s Wharf overview
  2. Daily Alta California, 17 Sep 1877, p2. Part of an announcement for the regular annual stockholders meeting, held at the Turn Verein Hall, Bush and Stockton streets.
  3. First mention of Rudolph Mohr as secretary of Alameda, Oakland and Piedmont Railroad Company, Oakland Tribune, 22 Sep 1879, p4. Last mention is 1893: The Manual of Statistics, Stock Exchange Handbook, 1893, p379 (Google Books).
  4. First mention of the Brewer’s Protective Association is SF Examiner, 10 Dec 1874. First mention of Rudolph Mohr as Secretary, SF Examiner, 2 Aug 1889, although I suspect he may have been secretary long before this, and may even have helped found the organization, as its founding coincides with his arrival in the city, and its function accords with his methodical business acumen. We shall never know. He began to be very prominent in the BPA beginning with the union struggles in the 1890s and 1900s, being quoted in the newspaper numerous times, and also taking the stand during hearings.
  5. Daily Alta California, 13 April 1884, p4.
  6. Daily Alta California, 27 Jan 1891, p2.
  7. SF Chronicle, 6 Sep 1892, p11.
  8. SF Call, 27 Dec 1896. SF Chronicle, same date.
  9. SF Call, 14 Jul 1897, p8.
  10. First instance in a newspaper for “Moneta Investment Co”” SF Examiner, 2 July 1902; offices were located in the Flood Building downtown San Francisco. Incorporation papers were filed 31 Jul 1902, according to the 1902 Biennial Report of the California Secretary of State, with capital stock of $25,000. Source: Google Books.
  11. SF Call, 6 Dec 21906, p2. The Grand Jury was big news then, there were many news features on the process of selection. During the extended period of questioning of the prospective grand jurors, Mohr was identified as “an admirer of Abe Ruef” in the SF Call, 28 Oct 1906 (p22). He was empaneled anyway.
  12. SF Call, 8 Jul 1908, p15; Daily Alta California, 8 Jul 1908. More than 60 lots in Sunnyside sold to Moneta.
  13. Real estate sales: SF Examiner, 30 Jan 1910, pp33, 38. Mohr and his sons had a practice of watching and waiting, then swooping in to make a profit on others’ poor decisions.
  14. The bulk of the references about Mohr’s Subdivision will be in main post, to come [this was written Jan 2022]. The first notice in reference to the pre-war houses is a mortgage for lots that will be 212 to 236 Gennessee Street, in SF Recorder, 1 Aug 1910, p8, from Title Insurance and Guaranty Co., presumably to finance the construction of the four houses (which have an erroneous date of “1908” in SF Planning Dept records). Supporting this, there is a reference to a theft of 500 feet of redwood lumber, reported by Rudolph Mohr, from a building site at Gennessee and Flood Ave, just where the four houses were built.
  15. SF Call, 27 Jun 1912, p14. In 1908 it was reported that Rudolph Mohr of Moneta Investment Co had purchased a Maxwell Runabout. SF Chronicle, 21 Aug 1908.
  16. SF Call, 27 April 1912, p24. The last I find in the papers is SF Examiner, 22 Dec 1944 – in a classified ad.
  17. The first instance of “Rudolph Mohr & Sons” in a newspaper I find is 27 April 1912 in SF Call (p24).
  18. SF Chronicle, 22 Feb 1914, p36. Such diverse interests for a quiet businessman.
  19. Building and Engineering News, 3 Dec 1919 (p18); SF Examiner, 20 Mar 1920
  20. Obituary: SF Examiner, 13 April 1928, p1. The work highlighted by the paper was Mohr’s presidency of SF Brewers Protective Association—before Prohibition, of course. Mohr was never president, only ever secretary of the BPA, but his prominent and vocal role in the organization during brewery/union struggles meant many would have remembered him for this, especially old-timers in the year 1928.
