The Bathtub Trust was when the Standard Sanitary Manufacturing Company and forty-nine other companies were charged with engaging in anti-competitive practices (price fixing etc). The trust had been around in some form or another since at least the turn of the century. A suite was filed against them, at the urging of President William Howard Taft, that began in Baltimore. [1] It reached the Supreme Court of the United States as Standard Sanitary Mfg. Co. v. United States and the trust was broken. [2] [3] Joseph R. Darling was a special agent of the United States Department of Justice who prepared the case. [4] In 1915 he wrote "Darling on Trusts" a legal treatise.
A subsequent criminal case was brought in Detroit, and in February 1913, members of the now-broken trust were found guilty of criminal conspiracy to restrain trade. [5]
