Simmons & Shapleigh
The Shapleigh and Simmons Hardware companies started as separate entities and rivals both based out St. Louis that eventually joined together in 1940. While business rivals both companies did very well and both Simmons and Shapleigh had a lasting personal friendship that included the families of both men. 
Each company had a variety of brands/trademarks used and 3rd party anvils sold throughout their histories making for a confusing history to understand.
To provide clarity I’ve listed the individual companies timelines side by side and then combined them in 1940 when they joined together.
There will also be special attention paid to Col. William Enders (June 27th 1851-June 5th 1930 ) who, while working for Simmons, developed the Wm Enders Oak Leaf brand.

1924 – Photo & associated description of Col. William Enders- Vice President, The Simmons Hardware Co. from Forty Years of Hardware by Saunders Norvell
Out of the past looms the handsome figure of Colonel William Enders of the Simmons Hardware Company. I can remember when I was a boy and our family attended Dr. Rutherford’s Presbyterian Church on Eleventh Street in St. Louis that Billy Enders used to be there to walk home with some of the belles of St. Louis. He was one of the handsomest young men I ever saw. It is needless to say how popular he was
with the belles of that day. However, he has lived and is still living at The St. Louis Club as a bachelor.
Colonel Enders for many years traveled in Texas with headquarters at Dallas. Afterward he was brought home and made a sales manager for the State
of Texas. There is not a hardware man who has ever lived who knew more hardware men in Texas or who knew more about the trade of Texas than Billy Enders. In St. Louis our desks were near each other and whenever a Texan came to St. Louis, he always made a bee-line for the Colonel’s desk.
How the Texas salesmen loved and still love their sales manager ! It was not necessary for him to ever wield the Big Stick. He ruled some twenty -five sales men just by the power of affection. His word to them was absolute law. When he called for certain results, these salesmen got the results or left their bodies on the field of battle ! In the management of the Simmons Hardware Company, the State of Texas was just left to Enders. When we had conferences, he spoke for Texas.
Then in business and outside of business, there is no more perfect gentleman than this same William Enders. I never knew him to do or to say a mean, un
charitable or unkind thing of any one. Sometimes when a situation would become a little tense, he would straighten everybody out with some smiling remark and a twinkle of the eye.
The Colonel is a great sales manager. He has held the affection of his customers and his salesmen for more than one generation. If I should analyze the Colonel after all these many years, I should say that if any problem comes up, he decides it, not with his head but with his heart and as his heart is big and true, his decisions are almost always absolutely right.
1930 – June 5th 11:15 p.m.
Col. William Enders dies at age 79 of heat disease at the Gatesworth Hotel where he resided. Survived by his widow Mrs. Ann H. Enders and a sister, Mrs. Davie Saunders. Buried in Valhalla Cemetery.
Born in Paducah KY. to Delia and Henry Enders. He entered the employ of the hardware company as a young man, being transferred first to Dallas, TX and then in 1900 to St. Louis.
