History
Summary
The Hoffmann Coffee Company of San Antonio, Texas was founded by William Robert Hoffmann in 1899. Hoffmann-Hayman Coffee begins in 1912 when Hoffmann merges with Merchants Coffee and partners with Mr. W. E. Hayman, its founder.
Mr. Hoffmann was married to Wilhelmina “Minnie” Menger. Minnie was the daughter of Dr. Rudolph and Catherine Menger. Catherine was the daughter of William L. Menger, owner of the Menger Hotel. When Mr. Hoffmann passed away in 1912, Minnie brought her brothers, Gustav P. Menger and Rudolph W. Menger, into the coffee business.
In 1920 the remaining partner, Mr. Hayman, sold his stake in the company to the Mengers. The company continued to expand and their new factory was constructed in 1932.
By July 1964, a San Antonio Express advertisement identified H & H Coffee as “A Division of the Continental Coffee Co.”, marking the company’s sale into Continental’s regional operations. Continental continued to use the 601 Delaware plant through the late 1960s and into the early 1970s (deed records and help-wanted ads from 1967 and 1970 still list the Delaware Street address), and in August 1972 G. P. Menger sold the Hoffmann-Hayman Warehouse Co. property at 601 Delaware to Kenneth L. Wagner—closing out the Menger family’s seventy-plus-year association with the address.
Since books haven’t been written about Hoffmann-Hayman yet, this history is being pieced together from newspapers, industry journals, and other sources.

Spanish-American War — Fort Sam Houston as national military staging base
The U.S. declares war on Spain on 25 April 1898. Fort Sam Houston—already a major Army post in San Antonio—serves as a national staging base, including Theodore Roosevelt’s Rough Riders mustering nearby. The military buildup cements San Antonio’s role as the commercial supplier to the U.S. Army’s southwestern operations.

Pure Food and Drug Act
President Theodore Roosevelt signs the first federal food-and-drug labeling law on 30 June 1906, prohibiting misbranded or adulterated food in interstate commerce. The act sets the regulatory backdrop for every roaster’s “100% pure” and quality claims in the decades that follow.

World War I begins in Europe
Austria-Hungary declares war on Serbia on 28 July 1914; the alliance system pulls the continent into a four-year conflict. Atlantic submarine warfare and disrupted European trade immediately pressure the Gulf-port green-coffee supply chain that San Antonio roasters—including H&H’s predecessor firms—depended on through importers such as J. Aron & Co.

U.S. enters World War I
Congress declares war on Germany on 6 April 1917. Fort Sam Houston’s role as a national staging and training base expands sharply—Camp Travis is built on adjacent land and trains multiple infantry divisions. The military buildup amplifies the institutional San Antonio market that H&H had already been building through the Fort Sam Houston account inherited with the Morrison acquisition that same month (March 1917).
Hayman sells out to the Mengers
W. E. Hayman sells his interest to the Menger siblings in January 1920. G. P. (“Gus”) Menger becomes president; R. W. Menger, secretary–treasurer; Mrs. William J. Schlosser (Minnie Menger Hoffmann) remains vice president.

Prohibition begins
The 18th Amendment and the Volstead Act take effect; the manufacture, sale, and transport of alcoholic beverages becomes federally illegal. Coffee assumes the role of the dominant public social drink in restaurants, hotels, and lunch counters. The shift almost certainly accelerated the 1920s expansion phase H&H entered immediately after the Hayman buyout — though a primary San Antonio source linking the two locally remains an open research thread.
Hoffmann-Hayman on Burnett Street
A 1932 article on the new Delaware Street plant notes that the company had already been at 331 Burnett Street for about ten years—placing H&H at the Burnett address from roughly 1922. This entry marks the Burnett Street plant generation rather than the 1932 Delaware Street build.

The Three Rivers Glass Company is chartered in Texas in early March 1922, capitalized at $50,000. At a directors’ meeting on Friday 17 March 1922, officers are elected for the first year: James Kapp as president, A. H. Morton as vice president, Charles R. Tips as secretary–treasurer, and H. S. Warrick as general manager (Warrick is in St. Louis at the time arranging machinery purchase). Other directors: Adolph Wagner, William L. Stiles, D. J. Woodward (all of San Antonio), and H. T. Harber (of Three Rivers). Construction of the factory at Three Rivers is ordered to start immediately, targeting operation within 60 days. Plant will use Three Rivers natural gas for fuel; glass sand from local pits; capacity 150 gross of bottles daily; first products soda-water bottles and milk bottles; target market Texas and Mexican trade.

New Deal NIRA — National Recovery Administration codes
President Franklin D. Roosevelt signs the National Industrial Recovery Act, creating the National Recovery Administration. NRA industry codes set price floors, wage minimums, and fair-practice rules for the food trade — including coffee roasting and wholesale grocery.

Ball Manufacturing Company of Muncie, Indiana — that the Three Rivers Glass plant has been purchased out of receivership for $130,000 and reorganized under the new name “Ball Glass corporation.” The plant had been in the hands of receivers since 1932; following a brief shutdown for inventory, renewed operations are projected within days. Production target: upwards of $500,000/yr in glassware for liquid-foodstuffs distributors across Texas, Arkansas, Oklahoma, and Louisiana; “the only glass manufacturing plant in South Texas.”

Smith, president of Hartford-Empire Co. of Hartford, Connecticut. Smith — questioned by Hugh Cox of the U.S. Department of Justice — defends Hartford-Empire’s ownership of the patents on the machinery by which glass containers can be produced most economically, its practice of leasing the machinery on a royalty basis to individual manufacturers, and its stipulation of what type of container each licensee may produce and, in some cases, how many. Hartford-Empire’s licensing terms also reserved the right to decide whether or not a new manufacturer is to be admitted to the business.

Pearl Harbor — U.S. enters World War II
Japanese naval aircraft attack the U.S. Pacific Fleet at Pearl Harbor; Congress declares war the following day. The home-front rationing regime that follows — coffee, sugar, gasoline, tin, rubber — drives H&H’s wartime packaging pivot to the Flav-O-Tainer paper bag in 1942 and constrains finished-goods inventory for the next four years.
Tin and metal rationing — War Production Board civilian-container restrictions
Following the U.S. entry into WWII, the War Production Board (established January 16, 1942) issued a cascade of Limitation Orders through the first half of 1942 restricting the use of tinplate, aluminum, and other strategic metals in civilian containers. Coffee roasters were directly affected: keywind tin cans, the standard 1930s package, became scarce. H&H’s response is documented in the brand line — the Flav-O-Tainer paper bag launches in 1942 specifically to replace tinned packaging, and the 1937 vacuum-can investment is partly stranded by the supply squeeze.

U.S. coffee rationing begins
The Office of Price Administration imposes nationwide coffee rationing — one pound per adult every five weeks, controlled by War Ration Book One stamps. Rationing runs through July 28, 1943, when shipping capacity improves. The eight-month window aligns precisely with the documented Flav-O-Tainer paper-bag run, and the OPA’s coffee-stamp regime is the strongest single national-policy / H&H-decision pair in the KB.

World War II ends
Japan formally surrenders aboard the USS Missouri in Tokyo Bay, ending WWII. Civilian rationing winds down through late 1945 and 1946 — tin, sugar, and coffee return to peacetime supply. H&H reverts to standard tin and glass packaging; the wartime Flav-O-Tainer line is retired as the supply constraint that justified it lifts.

Instant coffee national boom
By 1953, instant coffee had crossed roughly 17% of U.S. coffee consumption as Nescafé and General Foods’ Maxwell House Instant scaled national television advertising and supermarket distribution. The shift from roasted-ground to soluble coffee is the defining mid-century competitive pressure on regional roasters: convenience and shelf-life advantages favor national brands with continental marketing budgets. H&H’s response is documented as the 1957 Master Chef Instant Coffee launch — a defensive move into the category roughly four years after the national boom inflected.

Regional roasters like H&H — whose 1930s-1940s distribution had been built around rail freight and the Texas state highway system — face direct competitive pressure from out-of-state brands suddenly able to truck product into San Antonio cheaply.
