GBBA local #94 was a local union in Pittsburgh, Pennsylvania. At this time it is unclear when this union actually began. The present day international union, the GMP, has record that local #94 existed from 1943-1948 yet from the collection itself, there is evidence of union activity prior to 1943. This is indicated by the material found within the records. What complicates this matter is the fact that this material cannot be distinguished from the three or possibly more companies that may have been unionized in Pittsburgh under a local #94. The glass companies in which this collection draws from are the W.H. Hamilton & Company, the J.T. & A. Hamilton Company and Seaboard Glass Bottle Company.
The GBBA was founded in 1842 in Philadelphia, Pennsylvania. Over the years, along with several mergers, the GBBA has become the Glass, Molders, Pottery Plastics & Allied Workers International Union or GMP. The GMP is currently located in Media, Pennsylvania. The GBBA was a fraternity of workers who were led by local unions who were in return led by elected shop stewards, local union officers, and members who worked closely with the GBBA International to protect the interests of all GBBA members and their families.
John W. Heisler was the local #94 union President from 1943 to 1944 and also for the year 1947 until the union was dissolved in Pittsburgh. He was also the local union Recording Secretary at the same time as he was President. Mr. Heisler also served as Financial Secretary from 1945 to 1946. Little is known about local #94 in Pittsburgh, Pennsylvania and not much is known about the W.H. Hamilton & Co., J.T. & A. Hamilton Company and Seaboard Glass Bottle Co.
The W.H. Hamilton & Co. was started in 1863 and manufactured flint glass vials and bottles. Examples included high-grade flint prescription bottles and flint glass milk bottles. Their works were located at Railroad and Twentieth and Twenty-first Streets. Their offices were at first separate and were located in downtown Pittsburgh but later moved to the site of the works. In 1898, the factory moved to Charleroi, Pennsylvania on Monongahela Division, Pennsylvania Railroad while their offices remained in Pittsburgh. The Pittsburgh city directories last listing for this company is in 1908. It appears that it was here, at the family business of W.H. Hamilton & Co., that James T. Hamilton and Alexander M. Hamilton might have got their start in the glass industry.
The Pittsburgh city directory shows that during 1880 two brothers, James T. and Alexander M. Hamilton founded the J.T. & A. Hamilton Company at Twenty-sixth and Railroad Street, Allegheny Valley Railroad. The glass house manufactured flint glass bottles such as beverage, mineral and milk bottles, prescription vials, flasks and candy jars. Bottle marks that were used at first included an "H" in a triangle and later "J T & A H". Sometime around the turn of the century, the company expanded by adding a plant in Butler, Pennsylvania. The second glass house, known as the Hamilton Bottle Works, remained opened until 1919.
In 1943 Knox bought the J.T. & A. Hamilton Co. and the company was renamed the Seaboard Glass Bottle Company. The business remained at the same location and according to the Pittsburgh city directory, R.R. Underwood was listed as President, E.A. Schrag as 1st Vice-President and J.T. Hamilton as 2nd Vice-President. The company continued to manufacture glass containers and their trademark became an "S" in a keystone symbol. According to the Pittsburgh city directories, the Seaboard Glass Bottle Company remained in business until 1947-1948.
These records include by-laws, correspondence, financial material, ledgers, membership cards and other miscellaneous material pertaining to the GBBA, GBBA local #94, W.H. Hamilton & Co., J.T. & A. Hamilton Co. and Seaboard Glass Bottle Co. The records were collected by John W. Heisler while serving on various posts in local #94 and all are believed to be related to local #94. This collection, which spans from 1892-1954 is sparse and lacks many important details of local union #94. Information is also lacking on the other possibly involved local unions and of the day-to-day operations of the three respective glass factories.

The Local Union Series is arranged alphabetically by folder title and is by far the most extensive series in the record group. These records contain information regarding local union #94 and the interdependence it had with the GBBA. Included are correspondences, financial material, ledgers, membership cards, withdrawl cards, receipts, and recording secretary minutes. It is clearly demonstrated and documented that local union #94 was affiliated with the Seaboard Glass Bottle Co. from 1943-1948. From these years is where the bulk of the collection arises and is when John W. Heisler retained offices within the local union. Union material prior to 1943 does not allude to a specific company that housed the local #94 nor does it give any clue when this particular union may have been initiated. Thus, the records clearly show that there was a local union #94 in Pittsburgh, Pennsylvania housed by the Seaboard Glass Bottle Co. from 1943-1948. But there is evidence of a local union #94 prior to 1943 and to the Seaboard Glass Bottle Co. This is evident by examining the automatic feeder transfer cards, withdrawl cards and correspondence. There is also a ledger titled "roll book" for union meetings that dates from 1918-1946. There is also evidence of other local unions existing with in the respective glass houses other than local union #94. This is evident and documented in some of the ledgers as well. The collection does not allow one to conclude when local #94 was started, if it was ever housed in the J.T. & A. Hamilton Co., or if local union #12 was its predecessor or counterpart.
The ledgers primarily document an employee's compliance with paying dues and are normally recorded by employee name, year, and dues paid and how it was paid. Unfortunately these ledgers do not show who employed these union members or to what union they were paying dues. They also appear to be chronologically incomplete and thus do not help in giving insight to when local #94 or a preceding union within these glass houses may have begun. They also demonstrate that dues were initially collected every three months then were collected every two months and then every month. The ledgers, as well, contain notations about a particular worker regarding how they paid their dues, if they transferred, or were issued a withdrawl card. Notations were also made to document if one was suspended or expelled and whether that worker was re-admitted or re-initiated. In some of the later ledgers there were normally other documentations made that did not pertain to paying dues. Documentations include audits, balance in the treasury, cash, credits, and expenses.
The Miscellaneous Records Series is arranged alphabetically by folder title. This series contains various scant materials from the respective glass houses. Some of these materials are absolutely related to local #94 while others only appear to be. It also contains personal correspondence to John W. Heisler after local union #94 and Seaboard Glass Bottle Co. existed with suspected union brothers, and/or fellow employees, and friends. They give insight into their personal dealings at home as well as with employment. Again, the material is not enough to allow one to draw any conclusions to the exact existence of local union #94. One cannot determine from these records alone the factory or factories, besides the Seaboard Glass Bottle Co., that may have housed local union #94 and during what time frame.
