What You'll Learn
Leo Hendrik Baekeland's early life
Leo Hendrik Baekeland was born on November 14, 1863, in Ghent, Belgium. His father, Charles Baekeland, was a cobbler, and his mother, Rosalia Merchie, was a housemaid. Baekeland had an early passion for photography and developing pictures, which sparked his interest in chemistry. He attended the Ghent Municipal Technical School, where he studied chemistry, physics, mathematics, and economics. He was awarded a scholarship to the University of Ghent, where he received his bachelor of science degree in 1882 and began teaching as an assistant professor. In 1884, he received his doctorate in natural science, graduating with honours.
From 1882 to 1889, Baekeland taught chemistry at the University of Ghent. Between 1885 and 1887, he also taught chemistry and physics at the Government Higher Normal School of Science in Bruges, Belgium. In 1887, he was appointed Professor of Physics and Chemistry at the University of Bruges and returned to Ghent in 1888 as an Assistant Professor of Chemistry. In 1889, he married his professor's daughter, Céline Swarts, and they travelled to the United States on a travel scholarship. They visited New York City and met with Professor Charles F. Chandler of Columbia University and Richard Anthony of the E. and H.T. Anthony photographic company. Professor Chandler convinced Baekeland to stay in the United States.
Baekeland began working as a photographic chemist and soon found a position with Richard A. Anthony, Eastman Kodak's principal rival in the photographic business. He was highly successful and quickly took on greater responsibilities. He formed his own company to produce a new kind of film and became independently wealthy when it was bought out by Eastman Kodak in 1899. With his newfound wealth, he pursued his own chemical interests, including the development of Velox, a type of photographic printing paper that could be developed under artificial light. This invention further solidified his wealth and reputation.

The invention of Bakelite
Leo Hendrik Baekeland invented Bakelite, a polymeric plastic made from phenol and formaldehyde. Born in Ghent, Belgium, on November 14, 1863, Baekeland had a lifelong interest in chemistry. He studied the subject at the University of Ghent, obtaining a doctoral degree in 1884. He then worked as a professor of chemistry at the same university until 1889, when he travelled to New York on a fellowship.
During his time in New York, Baekeland worked for a photographic company and later set up his own business as a consulting chemist. In 1893, he invented Velox, the first commercially successful photographic paper that could be developed by artificial light. He sold the rights to this invention to the Eastman Kodak Company in 1898 for $750,000, a significant sum of money that allowed him to establish a laboratory to pursue his interest in synthetic resins and plastics.
Baekeland's goal was to find a substitute for shellac, a natural resin secreted by the female lac bug. He experimented with carefully controlling the pressure and temperature applied to phenol and formaldehyde, eventually producing a polymer that could be mixed with fillers to create a hard, mouldable plastic. This plastic, which he named Bakelite, was the first of its kind to retain its shape after being heated.
Baekeland obtained a patent for Bakelite in 1909 and founded the General Bakelite Company in 1910. The new material soon found many applications in the rapidly growing automobile and radio industries, as well as in the production of costume jewellery and car parts. With its excellent electrical insulation and heat-resistance properties, Bakelite played a key role in the expanding consumer economy and marked the beginning of the modern plastics industry.

The process of creating Bakelite
Leo Hendrik Baekeland invented Bakelite, the first commercially-used synthetic plastic, in 1907. It was made by combining phenol, a common disinfectant, with formaldehyde. The chemical name of Bakelite is polyoxybenzylmethylenglycolanhydride.
The A resin (resol) could then be made directly into a usable plastic. Alternatively, it could be brought to a solid B stage (resitol) in which, though almost infusible and insoluble, it could be ground into powder and then softened by heat to a final shape in a mould. Both stages A and B could be brought to a completely cured thermoset C stage (true Bakelite) by being heated under pressure.
In compression moulding, the resin is generally combined with fillers such as wood flour or asbestos fibre before pressing it directly into the final shape of the product. This process takes place under high pressure and heat and results in a hard plastic material. The moulding process has several advantages, including speed and the smooth surface that results.

The impact of Bakelite
Bakelite, the first commercially available synthetic plastic, was introduced by Leo Hendrik Baekeland in 1907. It was the first plastic invented that retained its shape after being heated, a property known as thermosetting. This revolutionary material, made from phenol and formaldehyde, marked the beginning of the modern plastics industry and had a significant impact on multiple industries and consumer goods.
One of the most notable impacts of Bakelite was in the electrical industry. Due to its excellent electrical insulation and heat resistance, Bakelite became the material of choice for radios, telephones, and electrical insulators. This helped to address the issue of the increasing cost of shellac, the only viable electrical insulator before Bakelite. With its strength, moldability, and low production cost, Bakelite soon spread to most branches of industry, including consumer goods.
The invention of Bakelite played a crucial role in the rise of affordable products during the early 20th century, particularly during the Jazz Age. For the first time, products could be quickly and easily mass-produced from materials that were previously considered industrial waste. This led to a wealth of inexpensive consumer goods flooding the market, improving accessibility and convenience for consumers.
However, Bakelite also faced some challenges. In its pure form, it was fairly brittle, so additives were used to make it more malleable and durable. Unfortunately, these additives affected the colour of the material, and when other plastics that held their colour better entered the market, Bakelite was gradually replaced by alternatives such as PVC, nylon, and polystyrene. Nevertheless, the impact of Bakelite as the pioneering synthetic plastic was profound, earning Baekeland recognition as the "Father of the Plastics Industry" and a place in the Plastics Hall of Fame.

The legacy of Leo Hendrik Baekeland
Leo Hendrik Baekeland, born on November 14, 1863, in Ghent, Belgium, is widely recognised as the "Father of the Plastic Age" or the "Father of the Plastics Industry". He immigrated to the United States in 1889, where he spent most of his career. Baekeland is best known for his invention of Bakelite, the first commercially available synthetic plastic, which marked the beginning of the modern plastics industry.
Baekeland's early life was marked by contrasting parental influences. While his father urged him to pursue shoemaking, his mother encouraged him to focus on education. Despite initial setbacks, he excelled academically and received his doctorate maxima cum laude from the University of Ghent at the age of 21. He taught at the university until 1889, when he moved to the U.S.
In 1893, Baekeland invented Velox, the first commercially successful photographic paper that could be developed under artificial light. He sold the rights to Velox to George Eastman and Kodak for one million dollars in 1899. With this money, he set up his own laboratory in Yonkers, New York, where he later invented Bakelite.
Baekeland's pivotal discovery came in 1907 when he successfully created Bakelite from phenol and formaldehyde. This material revolutionised multiple industries, including electrical insulation and consumer goods. Bakelite was the first plastic that retained its shape after being heated and had excellent electrical insulation and heat resistance. It was soon used in radios, telephones, and electrical insulators, and its applications spread to most branches of industry.
Baekeland received numerous awards and honours for his invention, including the Perkin Medal in 1916 and the Franklin Medal in 1940. He was also inducted into the Plastics Hall of Fame in 1974 and the National Inventors Hall of Fame in 1978. He obtained about 400 patents related to his creation, and by 1930, his company occupied a 128-acre plant in New Jersey. Baekeland died in 1944, leaving behind a legacy that transformed the world and laid the foundation for the modern plastic industry.
