Chapter 5 · 1924

The bob and the flat winding

After the First World War, women cut their hair — and the bob made every existing permanent-wave method useless overnight, because the spiral wind that Nessler and the machine age had built their apparatus around demanded length no bobbed woman had. In 1924 a Karlsbad hairdresser named Josef Mayer presented a different winding: the hair sectioned flat and rolled from its free ends toward the scalp, behind a scalp protector, with the moisture sealed in. The croquignole, or flat, winding made the permanent wave safe for short hair, fast enough for a salon business, and reproducible enough to conquer the world. This is the chapter the whole history turns on.

Two decades of engineering had carried Nessler's 1906 machine toward safety and speed — the differential heaters of Suter, the scalp protectors, the multi-head chandeliers — and not one of those improvements had touched the spiral wind at the machine's heart. The spiral demanded hair long enough to wind in a continuous coil along the length of a rod. The bob, blunt and jaw-length and worn by millions, was not. The most fashionable women of the decade were the very women the permanent-wave machine could not serve. The demand for permanence did not contract with the bob; it exploded. What was missing was not a better machine but a different idea about how to wind.

The bob

The bob arrived before the First World War and conquered the years immediately after it. A short, blunt cut, worn to the jawline or above — sometimes shingled to the nape — the bob was the visible signature of the modern woman: the flapper, the office worker, the dancer, the new voter. Its adoption was a mass event. By the early 1920s, across the cities of Europe and America, the long dressed hair of the Edwardian era had given way, in millions of cases, to short hair cut blunt and close.

The spiral wind of Nessler and Suter worked by winding the hair in a continuous coil along the length of a brass rod, so that the rod passed through the curl like a core. That demanded length: there had to be enough hair to wind spirally from the scalp outward. A bobbed head did not have it. Worse, the spiral method could not, as a matter of geometry, wave the first few centimetres at the root — a defect invisible beneath long dressed hair, but unacceptable on a short cut where the root was the style.

The machine age had carried the hot wave as far as the spiral would take it. The bob forced it the rest of the way — and the rest of the way required not a better machine but a different winding.

Waved short hair was not a niche demand. The flapper look — bobbed, softly waved, framing the face — was the defining style of the decade, and the women who wore it wanted the wave to last. Temporary Marcel waving on a bob was possible but daily; a permanent wave on a bob, in the existing methods, was not possible at all. The croquignole — a winding from the ends toward the scalp, treating the hair as a flat band rather than a bundled rope — proved the decisive answer. The idea did not belong, in its essence, to a single man; the croquignole wrap had antecedents in the trade. What made it a system belonged to Josef Mayer.

Winding from the ends

The croquignole, or flat, winding rests on two inversions of the spiral. The first is the direction of the wind. Instead of winding the hair from root to tip along a rod, the operator winds it from the free end — the tip — toward the scalp. The second is the shape of the section. Instead of bundling the hair into a rope and winding that rope spirally, the operator sections the hair flat, as a band, and rolls the band onto the rod. The rod lies flat against the head, parallel to the scalp, rather than projecting outward from it. The effect is a softer, broader wave than the tight spring-curl of the spiral, and a wave that begins at the root — because the last turn of the wind, the one nearest the scalp, carries the hair closest to it.

What elevated the flat winding from a technique to a system was the apparatus and process Mayer built around it — the system he would name REALISTIC. The patent record (principally US RE18,841, a reissue of his earlier filings) describes the method as a sequence. The hair is divided into flat sections. A protective clip is fixed to the scalp at the base of each section — anchoring the wind and, critically, shielding the skin from the heater and from steam travelling along the strand. The flat section is rolled from its free end onto a tubular roller, toward the scalp. The wound roller is wrapped in a fluid-soaked cloth, then enclosed in wax or parchment paper twisted at the ends into a sealed sachet that holds the moisture and the steam in. A sleeve-shaped electric heater slides over the packet and supplies the heat. The whole assembly is modular, repeatable, and — by the standards of the era — safe.

This is the point at which precision matters. Josef Mayer developed the practical REALISTIC system: the flat sectioning, the scalp protector as an integrated shield, the controlled tension of a rod lying flat, the moisture-retaining sachet, the sectional sleeve heating. He is not the inventor of croquignole winding itself — the wrap from the ends toward the scalp was an idea with antecedents in the trade, and the attribution of the croquignole to a single father is precisely what the American courts refused (next section). Mayer's contribution was not the bare idea of winding from the ends but the integrated, safe, fast, and reproducible system that turned the idea into the global salon standard.

Karlsbad, 1924

Mayer presented the system in 1924. The documented venue is the federal congress of Haarformer — hair-shapers — held in Dresden in October of that year, where he demonstrated the flat winding before the trade. (Popular accounts sometimes name Karlsbad, his base, as the place of presentation; the congress record places the public demonstration in Dresden, with Karlsbad the seat of the salon and school from which the method was taught. The 1924 date is firmly established.) Mayer was by then no obscure provincial. Born in 1881 in Parabuc, in the Hungarian Bácska — a region redrawn by the post-war settlements — he had trained deliberately and internationally across Budapest, Vienna, Fiume, Trieste, Milan, Genoa, Nice, Paris, and London, and had settled in the spa town of Karlsbad (Karlovy Vary), where his salon served a wealthy, multilingual clientele. He had begun systematic study of the permanent wave in 1909; the breakthrough came in the winter of 1923–24.

The headline figure attached to the system is the treatment time. Where the early spiral machines had kept a client in the chair for the greater part of a day — the often-cited six hours, and sometimes longer — the REALISTIC flat-winding system compressed a full head to roughly ninety minutes. (The figure is consistent across the trade literature and the memorial record; like all such numbers it varied with the hair, but the order-of-magnitude reduction — from hours to minutes — is the point that mattered.) Faster meant cheaper per client, meant more clients per chair per day, meant a salon economics the spiral machine had never achieved.

Nessler had answered the question of whether a curl could last. Mayer answered the question that followed: whether it could last on the hair the modern woman actually wore — short, bobbed, and cut close to the root the spiral could not reach.

Why it conquered

The flat winding won the salon for three reasons, each verifiable from the apparatus rather than from the advertising of the period. First, it worked on the bob: the wind from the ends, the flat section, and the rod lying parallel to the scalp made short hair waveable for the first time and brought the root — the impossible first centimetres of the spiral — within reach. The bob was the dominant style of the decade; a method that served it had an addressable market the spiral machine had lost.

Second, it was fast. The compression to roughly ninety minutes turned the permanent wave from a specialist, day-long service into an ordinary salon appointment — more clients per chair, lower cost per treatment, a wage for the operator rather than a fee reserved for a handful of metropolitan specialists. The mass market opened with the flat winding and not before it. Third, it was reproducible. The modular process — flat section, scalp-protector clip, roller, fluid-soaked sachet, sleeve heater — could be taught, standardised, and certified. Mayer built his Karlsbad school to do precisely this: night-time courses for masters and journeymen, international competitions to disseminate best practice, and (from 1927, with the Mayer Realistic Karlsbad company) a worldwide agency network with offices in New York, Melbourne, London, Paris, Vienna, and Berlin. By the late 1920s the croquignole, embodied in the REALISTIC system and its imitators, was on its way to becoming the global salon standard — the method against which every later winding, down to the modern salon rod, would be measured.

The patent estate and the patent wars

The flat winding's commercial success made its patents valuable, and valuable patents in the American salon trade of the late 1920s and 1930s meant litigation. The Mayer patent estate — the American originals and reissues (US 1,619,794, US 1,894,612, US RE17,585, US RE18,841) and the European family (GB 251688A, FR 593464A, BE 335190A) — became the centre of a sustained campaign of enforcement in the United States. The documented vehicle for that enforcement was the Philad Company, the American assignee through which the croquignole patents were pressed against the trade. The fullest account belongs to the Mayer memorial; what follows here is the verified core, with the limits of the evidence stated plainly. See the patent wars → — a cross-cutting sidebar that gathers the croquignole litigation of the 1930s–40s, including the cases that broke RE 18,841, into one reference.

The single most important correction the courts made to the popular record concerns Mayer's own standing. In the 1932 case Naivette, Inc. v. Bishinger — a Sixth Circuit decision (61 F.2d 433) that invalidated Robert Bishinger's croquignole clamp patent (US 1,718,025A, filed 1926, granted 1929) for want of novelty — the court explicitly rejected the claim that Mayer was "the father of the Croquignole wave." The croquignole wrap, the court found, had antecedents; Mayer had not invented the winding itself. What he had done — and what the patent estate protected — was develop the integrated system around it. That distinction is the hinge of the whole chapter: Mayer the developer of the practical REALISTIC system, not Mayer the inventor of the croquignole. Both the popular legend and the patent claims ran past it; the court pulled them back.

Bishinger belongs in this account rather than in Chapter 4 because his patent is a croquignole tool — a ratcheted wooden winding roller with padded bases — and the case that bears his name is a croquignole-era case. He was an American, of Pittsburgh, not a European machine-age inventor, and his 1929 patent postdates the spiral generation entirely.

The commercial scale of the enforcement, as it reached the federal courts, is documented in two record-anchored figures. In the 1932 Naivette litigation the trade referred to more than three thousand croquignole machines in the American market and sums on the order of a million dollars. By 1940, in National Hairdressers' and Cosmetologists' Association v. the Philad Company (34 F. Supp. 264), the campaign is recorded as reaching roughly five thousand salons, across some fifty-seven cases, with annual licence revenue on the order of twelve dollars per salon per year and aggregate receipts around sixty thousand dollars a year. These figures are attributed to the court records; they describe the enforcement campaign, not the whole market, and they are stated here as the verified core rather than inflated.

Three further points must be handled with care, because the evidence is thinner than the popular account implies, and overstatement would betray the record. First, the Cincinnati Realistic Permanent Wave Machine Company was founded by Philip D. Spaeth in 1925 — not by Mayer. Mayer licensed the technology; the American manufacturing and enforcement vehicle was Spaeth's. Second, the 1944 judicial sale of the reissue patent RE 18,841 is documented as an event, but the purchaser and the precise character of the proceeding are not established in the open record; it should not be asserted as an insolvency. Third, the later purchase of "The Realistic Company" by Revlon in 1960 is a documented brand lineage, but the chain of title from Mayer's patents to that brand is not proven, and is stated here only as a parallel history, not as a descent. The memorial carries the fuller account; the chapter carries only what the documents bear.

The figure behind the system

Josef Mayer was, by every measure, the developer of the practical system that carried the permanent wave into the modern salon. He was not the inventor of the croquignole winding in the bare sense the 1932 court policed — the court said so plainly — and to call him "the father of the Croquignole wave" is to repeat a claim the record rejects. But the integrated REALISTIC system — flat sectioning, scalp-protector clip, sealed moisture sachet, sectional sleeve heating, controlled tension, roughly ninety-minute treatment time — was his. So was the business around it: the Karlsbad company founded in 1927, the worldwide agency network, the school that trained operators across twenty-two countries, and the international competitions that made Karlsbad the centre of the art for a decade.

His later life was harder than his triumph. The internationalist who built a business across borders became, in the 1930s, a target of the National Socialists: his cosmopolitanism, his lodge membership, and his Czech and international contacts were held against him, his company was confiscated under "Aryanisation," and a national administrator was installed. After the war, the firm was restructured out of all recognition — by 1946 it had begun making industrial furnaces for the porcelain works around Karlovy Vary, and today survives as a heavy-industrial firm whose name is the only echo of the salon it once was. Mayer died in Darmstadt on 5 January 1952, and is buried there.

The full life — the biography, the complete patent estate with the seven PDFs, the litigation record in detail, the photographs and the "Ten Years of Realistic" commemorative material — is the subject of a separate memorial site, maintained by his descendants. This chapter is the spoke; that site is the hub.
