The formative period of the two older organizations furnished opportunities for a study of the disability benefit and showed its usefulness in strengthening the national unions. These organizations, however, experienced grave difficulties in their attempts to administer disability insurance. The Engineers included “totally disabled members” among the beneficiaries of the fund provided for in 1866.[40] The by-laws of the insurance association founded by the Brotherhood on December 3, 1867, provided for assessments of 50 cents per member for the benefit of each totally disabled member—one half the amount assessed in case of death.[41] The history of this benefit was tersely summed up by General Secretary-Treasurer Abbott in his address to the Engineers’ Association, December 3, 1871: “The Baltimore convention, 1869, adopted a disability clause, the Nashville, Tenn., convention amended it, and the Toronto, Canada, convention, 1871, repealed it.” At St. Louis, 1872, the Brotherhood formed a separate association, known as the “Total Disability Insurance Association,” for furnishing insurance against disability to members.
