Karl Ludwig Nessler, later known as Charles Nessler and Charles Nestle, was an American hairdresser, inventor, and entrepreneur. He developed the first commercially successful machine permanent wave, patented related hair-treatment devices, established an international salon and manufacturing business, and wrote books on hair care and hair loss.
Background
Karl Ludwig Nessler was born on May 2, 1872, in Todtnau, a town in the Black Forest of Baden-Württemberg, Germany. His father, Bartholomew Nessler, was a shoemaker, and his mother was Rosina Laitner. Nessler briefly apprenticed as a barber before leaving his native region for work in Switzerland and later pursuing hairdressing in European cities.
His early employment included factory work involving small electrical appliances and watch parts, experiences that gave him practical familiarity with simple mechanical and electrical equipment. He subsequently worked in hairdressing shops and studied established waving techniques in Paris before moving to London. In business and public life he used the names Charles Nessler and Charles Nestle, adapting his German identity to the international markets in which he worked.
Career
Nessler began his professional life with a short barbering apprenticeship and employment in Switzerland before working as a hairdresser in Geneva, Paris, and London. In London he opened his own salon in 1901 and developed a method for producing a lasting wave by combining an alkaline preparation with heat applied to hair wound around rods. He publicly demonstrated the process in 1906, and his British patent for an improved process of waving natural hair followed in 1909, with further mechanical improvements in subsequent years.
The permanent wave was a major technical and commercial achievement in beauty culture. Nessler's apparatus used heated rods and chemical treatment to reshape hair so that the curl survived washing, while his later patents addressed hair-waving devices, hair-testing equipment, artificial eyelashes, and related cosmetic technologies. The work joined craft knowledge with practical experimentation during a period when electrical appliances and standardized salon services were transforming personal care.
Nessler moved to the United States in January 1915 after wartime restrictions disrupted his British business. He established a salon in Manhattan and expanded through additional locations, manufacturing operations, and the Nestle Company. By the late 1920s his enterprises included salons, beauty-parlor equipment, hair preparations, and cosmetics; in 1928 he sold the business, production facilities, and patents to the Nestlé-Le Mur Company. He continued researching hair and developing hair and skin-care products until his death in Harrington Park, New Jersey, on January 22, 1951.
Achievements
Nessler developed and commercialized the first machine permanent wave, combining heated rods with chemical treatment so that artificially curled hair could retain its shape after washing. The invention became a foundation of modern permanent waving and helped establish mechanized beauty salons as a major form of personal-care business.
Nessler patented and marketed additional hair technologies, including artificial-eyelash equipment, hair-waving devices, and apparatus for testing hair elasticity and absorption. These inventions extended his work from a single salon technique into a broader system of cosmetic engineering and hair-care products.

Religion
Nessler was a Roman Catholic. His religious affiliation belonged to the Catholic tradition that shaped religious and social life in the German-speaking regions where he was born and raised, before his later career in Britain and the United States.
Views
Nessler treated hair as a subject linking practical craft, bodily care, and broader questions about health and human character. His writings and commercial activities reflected an effort to establish hairdressing as a systematic field based on observation, classification, measurement, and experimentation, although some of his theories about hair growth and baldness were later regarded as unsupported.
Personality
Contemporary descriptions portrayed Nessler as affable, paternal, understanding, and energetic in dealing with salon clients and employees. He was also described as intensely absorbed in hair research and as maintaining a private laboratory for experiments on hair growth, hair treatment, and baldness.
Quotes from others about the person
The New Yorker described Nessler as affable, paternal, understanding, and gallant with clients, while noting his continuing personal involvement in advising salon operators and experimenting with hair treatments.
Interests
Hair science, cosmetic technology, hair treatment, and the development of beauty equipment.
Connections
Nessler was the son of Rosina Laitner and Bartholomew Nessler, a shoemaker. He married Katherine Laible, a fellow employee, on August 13, 1901, and they had four children. His family remained connected to his personal and business life while his career expanded between Europe and the United States.
