Jacob Bartholomew (December 1823 - June 9, 1906) was an American prospector and inventor of a gold-finding instrument referred to as an "indicator," this being a 10 inch (25.4 cm) flat steel spring fitted into the neck of a hermetically sealed vial containing a mystery substance.

Mr. Jacob Bartholomew Returns From the Mountains A Rich Man.", The Opinion-Tribune (Glenwood, IA): 6, 18 Nov. 1897, https://www.newspapers.com/newspage/33434295/, "To cut a long story short, he has an 'indicator,' an instrument for finding gold that never misses. It is a sure shot on a gold mine every time and all that is necessary to be done is to turn the machine loose and the gold mine is immediately located."

- "A Mysterious Instrument.", Opinion-Tribune (Glenwood, IA): 18, 13 Oct. 1898, https://www.newspapers.com/newspage/4032567/, "The wizzard's wand which he carries is a very simple looking affair, consisting only of a bit of flat steel spring about ten inches long, on one end of which is a small vial, the spring being inserted in the neck of the vial and the opening then hermetically sealed. The mystery is hidden within the vial. Mr. Bartholomew says there is but one man besides himself in all the world who knows all the ingredients that go to make up the liquid contents. He defies detection by analysis, claiming that chemists are baffled in the attempt to specify all the ingredients. He keeps his strange secret strictly to himself but never hesitates to put his invention to test when asked to do so[...] He makes a flat denial to the theory that there is no magnetic attraction in gold and silver, and seems to prove it to the satisfaction of many in the use of the little steel spring and vial with its strange compound. He claims that it requires the combined effects of the electricity of the human body and the influence of the compound in the vial to produce the required effects."
