Founded in 1908, the “Simplfied Speling Soesiety” were certainly not the first such group (despite the title of their journal). The desire to whip the oddities of English spelling into some kind of more logical order can be traced back to the 16th and 17th centuries, and gathered particular pace in the late 19th century with the efforts, for example, of the American Philological Society who, in 1876, recommended the adoption of eleven reformed spellings for immediate use — are→ar, give→giv, have→hav, live→liv, though→tho, through→thru, guard→gard, catalogue→catalog, (in)definite→(in)definit, wished→wisht. One major American newspaper, the Chicago Tribune — whose editor and owner, Joseph Medill, sat on the Council of the Spelling Reform Association — actually began to use these new spellings.
