Who In The Heck Was Marcus Sass?

 Here is yet another western bitters bottle which seems to have some mystery surrounding it. This bottle was unknown in embossed form until a dark amber example was discovered in the Red Bluff, California area in the late 1980s. Prior to this discovery, it was believed that this brand was a label only bitters. Wilson's 1968 reference book on western bitters indicates the inventor of this oddly named concoction was a Amandus Sass of San Francisco,( Marcus)? and other bitters reference books also collaborate this. I have not seen any advertisements or trade mark information which would make this bottle's origin more clear. I understand that it dates to 1876, or 1877. Apparently it was only produced for a short time as they are extremely rare bottles. I only know of two complete examples...the original discovery in dark amber, and this "old amber" specimen.In my collection I also have the bottom half of one which was dredged up in San Francisco bay many years ago, and it is an olive amber. There was also a broken in place example found in the Bay Area a few years ago. I have seen photos of this one and it almost looks like a probe skewer, but hopefully this was not the case.
 The example shown was recovered in 2001 in the San Francisco Bay area as well. It would appear that while there were indeed several batches blown. due to the differences in color shade, this brand was not distributed as widely as other brands of bitters.
 If anyone has any additional information on other pieces or whole examples known, I would certainly appreciate it. Also, it would be interesting to know if there have been any shards, or advertising in other western states. DM
