A couple of references on the net suggest that Syracuse Salt Potatoes were developed by Hinerwadel during the 1930s. March 2007: Robin Augello notes that the "famous salt potatoes were not invented during the heyday of salt production but in the 1930's by a local business, Hinerwadel's, for the seasonal clambakes they hosted."
The local salt museum claims:
"In the 1700s & 1800s, perhaps even earlier, this Salt plant produced almost all of the nations salt. Add the salt production to the Erie Canal and you can see what a prosperous location Syracuse was during that time. Water taken from the Onondaga Lake was boiled down, or set out in the sun for evaporation in huge bowls. As most of the workers were Irish they brought along their potatoes for their meals and would place the potatoes in the boiling vats to cook giving you the famous salt potatoes. Syracuse is well known for its salt potatoes to this day! (Nowadays all they are, are very small potatoes boiled whole with the skins on in very salty water. 4 lbs potatoes to 1 lb of salt). Eat these dipped in melted butter and you have a great treat. By the 1870s this way of making salt was obsolete and the factory folded. "
The museum, salt potatoes, and the Hinerwadel claim can be found on the Roadside America site.
There is some documentary evidence to support the Salt Museum's story, including this recipe from a book published in 1902:
SYRACUSE HOT SALT POTATOES (THE CATERER)
Select potatoes of medium size and smooth skin and scrub clean; have ready a kettle of brine at the boiling point; put in potatoes, cover and boil until tender; remove from the water and drain. Serve at once. The outside will be covered with salt crystals and the inside will be white and mealy.

A description of the work involved in making salt, and of the work force in the 1860's can be found in this 1863 book studying ways that women could make money in that era:
A gentleman in the salt business at Geddes, N. Y., writes : "There used to be employed far more women than now in making bags to hold dairy or bag salt. Now, sewing machines
have entirely superseded them in this branch of our business. During the summer season, formerly, there were from one hundred to three hundred women at bag making. There are now, say one hundred or more women engaged in packing and filling the barrels with salt. They are all foreigners. It is dirty, heavy, and laborious work, and not suitable for women, but is extremely healthy. No difference is made in the price paid men and women, all being paid by the piece, and earning from 75 cents to $1 per day. A strong woman can learn very soon. The amount of work, probably, will not change much in future. The work is done only in the summer season. A large proportion of all the salt made in this country is made here. The annual product of our salt springs is about seven million bushels salt, produced at an expense for labor of not less than ten cents per bushel. Nearly all is paid to men, Irish and Dutch getting the most of it. A very small part of the work, if any, is adapted to women. Most of our women workers are the wives or mothers of men and boys I who fasten hoops on barrels. Most of the salt at Syracuse, N. Y., is made by boiling down the water that springs from artesian wells. At Turk's Island, salt is made by simply digging vats in the meadow and throwing the water into them. As it rarely rains there for a number of months, they require no covering to their works, and have only to take out the salt and stack it up when it is made."

Crossroads in Time: An Illustrated History of Syracuse
By Dennis J. Connors, page 28, indicates that in the 1820s and 1830s there were "modest number of Irish Catholic salt workers at Salinas." Page 67. There was a larger influx of Irish and German immigrants in the late 1840s.
Wedding of the Waters: The Erie Canal and the Making of a Great Nation, By Bernstein, Peter L. 2006: "Many of the salt workers [in the Syracuse area] were Irish, who introduced both potatoes and corn soaked in salt into the local diet. These dishes are still a local specialty in Syracuse." Page 190.
Bernstein cites an authority at footnote 17, but that footnote is not part of the online preview. [The Bergen County system has the book available, and on its way to me.]
Hinerwadel was involved in a trademark suit with Rapasadi & Sons over salt potatoes; this article has some interesting history, not directly relevant to the origin of the dish. It does say that Hinerwadel was founded in 1914, well after the Syracuse Hot Salt Potatoes recipe published in 1902.

Note: I'm collecting these references, partly for the fun learning about the Erie Canal and Syracuse, but partly to send on to the Salt Museum so that the Syracuse Salt Potato will be credited properly and not ceded without a fight to a commercial enterprise.]
