Henry Gottlieb Eckstein

Retired as general superintendent of N. K. Fairbank manufacturing (Chicago, St. Louis, Canada) in October 1898; bought an active interest in F. W. Rueckheim & Bro. by 1899 and became treasurer
Developed the moisture-proof Cracker Jack package (bag in use 1899; Eckstein Triple Proof Package): U.S. Patent 797,504 "Paper carton" (filed 25 July 1903, issued 15 August 1905) and U.S. Patent 881,561 "Moisture-proof package" (filed 6 December 1904, issued 10 March 1908)
Firm renamed Rueckheim Brothers & Eckstein in 1902 or 1903; package made national grocery distribution and a prize-in-box possible; died 11 April 1935 in Upland, California

Henry Gottlieb Eckstein invented the package without which there is no individual Cracker Jack box, no national grocery run, and no prize to hide. Street popcorn was already a cheap American habit when he was a boy in Chicago. Frederick William Rueckheim, recorded separately, turned that commodity into a named confection. Louis Rueckheim, also recorded separately, dried the coat so the kernels would stay separate. The evolution of the brand (two years, two naming stories, a box, a prize whose date will not sit still) is covered in "That's a crackerjack". This record is the box. Without wax, moisture wins. Without a sealed carton, Cracker Jack stays a Chicago scoop.

The three men stay in the same house. Frederick ran strategy and marketing. Louis ran manufacturing. Eckstein closed the package. Samantha Chmelik, in the German Historical Institute life of the older brother, is explicit about the industrial order: from 1872 to 1899 the Rueckheims sold popcorn goods, and then Cracker Jack, in large wooden tubs. Retailers scooped the mix into their own boxes or bags. Portion and freshness were whoever held the scoop. A dry coat without a package is still a local trade. A name without a package is still a Fair novelty. The problem left after 1896 was moisture in transit.

Chicago, soap, cottonseed

Henry Gottlieb Eckstein was born in Chicago on 15 January 1860, son of Charles and Julia Eckstein. Both editions of The Book of Chicagoans print that date and that city. He was German by descent and Illinois-born. The 1905 book gives private schools and one year in a public school. The 1911 book says private and public schools. That is the childhood on paper.

He went to work at twelve for N. K. Fairbank & Co., the Chicago soap, lard, and cottonseed-oil house. The 1905 book has him beginning at the bottom of the ladder. In 1883 he invented the Filter Press Steaming Process for the extraction of fats from Fuller's earth. In 1885 he was placed in charge of the soap manufacturing department. In 1888 he became superintendent of all manufactured products in the Chicago factory (1905) or general assistant superintendent of those products (1911). In 1891 he invented the Eckstein Process for deodorizing cottonseed oil. The American Oil Chemists' Society later listed that 1891 work as the first industrial-scale American deodorizer: live steam blown through alkali-refined oil at high temperature, at atmospheric pressure, without the vacuum David Wesson would add around 1900. In 1898 Fairbank made him general superintendent of the manufacturing departments in Chicago, St. Louis, and Canada. He retired in October 1898 because of ill health.

Jane Lear, in the Oxford Companion to Sugar and Sweets entry hosted by WTTW, identifies him as a former general superintendent of N. K. Fairbank. That matches the 1911 book. The soap years are why a retired process man would think in wax, moisture, and a seal that could leave a plant.

He married Emily L. Wegner on 19 April 1883. She died 25 July 1885, leaving a daughter, Lillian B. He married Louisa M. Rau on 9 July 1887. The 1911 book names two children of that marriage: Henry G., Jr., and Myrtle L. Those names belong to a family firm later. They are not a second biography.

A pew, then a share

Chmelik has him attending the Oakland Methodist Church with the Rueckheims. Joe Blackstock's 2011 Daily Bulletin column, written from the Upland house, says he met the brothers at church. The pew is the connection the scholarly life will hold.

The year of the handshake wanders. Chmelik dates the retirement to 1898 and the moisture-proof bag to 1899. F. E. Ruhling, writing in Printers' Ink on 7 April 1921 as GG Archives reprints him, dates Eckstein's arrival to 1898. Plei has him joining in 1897, when the firm rented a store at 316 South Clinton Street, and, earlier in the same piece, "by 1899." The Book of Chicagoans, in both editions, is more precise about money and less precise about the first day: in 1899 he "bought an active interest in firm of F. W. Rueckheim & Bro., makers of Cracker Jack and candies, shortly afterward incorporated as Rueckheim Bros. & Eckstein, of which has since been treas." Chmelik adds that Paul Fernald, Emma Rueckheim's first husband, sold his interest in the firm to Eckstein in 1899. Print the scatter. 1897, 1898, and 1899 are all on paper. This atlas does not pick a silent winner.

Chmelik has him treasurer in 1899. The 1905 and 1911 books agree he was treasurer of the renamed firm. The rename itself will not sit still. Chmelik, Wikipedia's Cracker Jack page (used here as a finding aid), and the Cracker Jack Collectors Association use 1902. Lear uses 1903. Plei uses 1902 for incorporation and 1903 for the Harrison and Peoria factory. The Encyclopedia of Chicago company entry, which this record retrieved, does not mention Eckstein and does not date the rename. The 1905 book, already in print two or three years after the change, only says "shortly afterward." The year of the letterhead can wander. The industrial fact does not.

Triple Proof

From 1872 to 1899 Rueckheim popcorn was scooped from wooden tubs. That is Chmelik, and it is the reason this life exists. Louis had already remade the coat. A dry, crispy molasses shell kept kernels separate. The problem left was moisture in transit. Candied popcorn, Eckstein later wrote in a patent specification, will not keep "for more than a few days" in an ordinary carton.

Ruhling is the period witness for the sequence. First, an inner waxed carton. After it was filled, it went into an outer or printed carton. Later, a wax-sealed wrapper of flexible paper enfolded the waxed carton, sealed at the ends, and made the product "impervious and commercially moisture-proof." That, he wrote, was "the start of Cracker Jack's general distribution." Once the wrapper existed, "it became possible to ship this perishable product across the continent and market it in substantially as crisp and delicious a state as when it left the mixing machines in the factory kitchens."

The mixing machines are Louis's. The wrapper is Eckstein's. Ruhling is the man who said the two inventions had to meet.

The 1911 Book of Chicagoans is the period name in Eckstein's own directory voice: inventor of the Eckstein "Triple Proof Package," a dust, germ, and moisture proof paper package. Wikipedia and company lore use the same three adjectives. They are not a later coinage. Plei prints "Eckstein Triple Proof Package" as the name then in use. Lear is more cautious. The wax-sealed package, she writes, was developed in 1899; moisture-proofing followed three years later. He "did not actually invent the packaging, but paid a German scientist $500 to teach him how to make wax paper" and then improved the process. That $500 scientist is Lear's. An independent source for the payment was not retrieved. Print it as her caveat. The patents that follow are Eckstein's name on the paper.

Chmelik dates the moisture-proof bag to 1899 and the patent to 1904. The 1904 date is a filing, not a grant. Two specifications sit in the file.

U.S. Patent 797,504, "Paper carton," was filed 25 July 1903 in Eckstein's name and issued 15 August 1905. The specification is a stiff Manila blank, cut and scored first, side edges glued, then the open-ended tube dipped in melted paraffin so the scores and the sealed seam take wax. Ordinary waxed sheet, scored after coating, cracked at the corners. Glue would not hold on a pre-waxed overlap. Dip after scoring and the carton is "substantially moisture-proof at all points" when the flaps fold. The goods named include candied popcorn, which becomes "sticky and soft, and so unsalable" after a short exposure. Inclosed in that carton, he wrote, the confection "may be retained for weeks in dry and brittle condition."

U.S. Patent 881,561, "Moisture-proof package," was filed 6 December 1904, assigned to Rueckheim Bros. & Eckstein, and issued 10 March 1908. It cites 797,504 as the earlier carton. The later specification is a stiff inner carton, an outer wrapper of flexible paper supersaturated with wax (forty-five to fifty-five percent of the sheet's weight, not the ordinary ten to twenty-five), and folds sealed by melting that wax. The goods named include pop-corn and other items that "deteriorate and become stale on exposure to the air." A package so sealed had been found to "preserve intact for months in an atmosphere saturated with moisture, such goods as candied pop-corn." An outer printed jacket protected the seal and carried the brand.

That is the box. Dust-proof, germ-proof, moisture-proof is the directory slogan. A stiff waxed carton plus a supersaturated wrapper plus heat-sealed folds is the specification. Without it there is no consistent portion, no brand on a grocery shelf, and nowhere to put a prize. The prize year is contested and belongs to the evolution chapter. The package made a prize possible. The year of the toy is another argument.

A name on the door

The new letterhead coincided with a factory that covered a city block at Harrison and Peoria, built for $125,000. Plei dates that plant to 1903 and names Joseph C. Llewellyn as architect. By 1912, Chmelik and the Encyclopedia of Chicago agree, about 250 men and boys and 450 girls and women worked there. A Brooklyn plant followed in 1914. Those rooms are Frederick's expansion as much as Eckstein's. This record keeps them only as the rooms a sealed carton left.

Company ads, Chmelik writes, typically stressed the protective wax wrapper and the freshness of the products. That is the marketing of a package. In February 1922 the directors dropped the founders' names. The company became The Cracker Jack Company, because buyers knew the product and did not care who made it. Ruhling is the period witness: only "an infinitesimal percentage" of the people who ate Cracker Jack had any idea who made it, "and they did not care." The product had eaten the firm. The package had made that possible.

Sailor Jack and Bingo reached the box in 1918. The boy is documented: Robert Rueckheim, born 1913. The dog is not a closed case. The Collectors Association identifies Bingo with a stray named Russell that Eckstein adopted in 1917 and "demanded" appear on the packaging. The Chicago and Cook County Cemeteries page names the stray Russell and does not assign an owner. Chmelik could not find a reliable source. One sentence is enough.

Upland, April 1935

The 1911 book lists membership in the Diana Hunting and Fishing Club and a residence at 5312 East End Avenue. Blackstock has him first coming to the Inland Valley in 1911 to get away from Chicago winters, and later building a winter house on Euclid Avenue in Upland, designed by Reginald D. Johnson, in 1931. After Louis died in 1927 and Frederick in January 1934, Plei and the Made in Chicago Museum page have Eckstein as president, briefly, before the chair passed to Frederick Jr. A contemporary board minute was not retrieved. The industrial life does not depend on the title.

Henry Gottlieb Eckstein died in April 1935 in California, age 75. Find a Grave, retrieved as HTML after a Cloudflare block, gives 11 April 1935 and Upland, San Bernardino County. Blackstock places the death at San Antonio Community Hospital after a heart attack. Plei places it at his home in California. The day and the town are stable on the memorial. The room is not. He is buried at Oak Woods Cemetery in Chicago, with the Rueckheims in the same ground.

Louisa remained in Upland until 1939, as Blackstock has it. Henry G. Eckstein, Jr., worked for the company and, Plei writes, died in August 1963. The Rueckheim family sold The Cracker Jack Company to Borden in 1964. Borden sold the brand to the Frito-Lay division of PepsiCo in 1997. The sealed carton Eckstein patented still sits behind that corporate ownership.
