The Life and Innovations of Hippolyte Mège-Mouriès: Inventor of Margarine

Hippolyte Mège-Mouriès, born on October 24, 1817, in Draguignan, France, was a pioneering French chemist who made significant contributions to applied chemistry, most famously for inventing margarine. His early career began at the central pharmacy of the Hôtel-Dieu hospital in Paris, where he honed his skills as a pharmacist. This work laid the foundation for a series of notable innovations, particularly in the fields of medicine and food chemistry. One of his early contributions was the refinement of the syphilis medicine Copahin, making it more effective for medical use. Additionally, Mège-Mouriès secured patents for a wide range of innovations, including effervescent tablets, which became a popular delivery method for medications, and advancements in paper-making and leather tanning techniques. These accomplishments underscore his versatility as a chemist who sought practical solutions to industrial and medical challenges.

In the 1860s, France faced a severe butter shortage, prompting Emperor Napoleon III to announce a competition for a satisfactory butter substitute that could meet the demands of the military and lower-income populations. Mège-Mouriès rose to the occasion, beginning experiments with animal fats and dairy. He ultimately developed a product made from processed beef tallow and skimmed milk, which he named oleomargarine. This product, later shortened to margarine, mimicked butter’s qualities while being far cheaper and more accessible. His innovation won the prize in 1869, and the recognition of margarine soon spread beyond France, gaining patents in other countries, including the United States, where he obtained a patent in 1873. This invention revolutionized the food industry, offering a low-cost alternative to butter that became a staple in kitchens worldwide.

Mège-Mouriès’s interests extended beyond margarine. He worked to improve the nutritional value of food, enhancing chocolate by adding calcium phosphate and protein. His research into bread production also earned him international acclaim and multiple gold medals. His work in food chemistry helped address issues of nutrition and food scarcity, making him a key figure in 19th-century science. He passed away on May 31, 1880, in Neuilly-sur-Seine, leaving behind a legacy of innovation that continues to be celebrated.

Patricia Era Bath: Laserphaco Inventor

Patricia Era Bath, a trailblazing figure in the field of medicine, left an indelible mark with her groundbreaking contributions, particularly the invention of the Laserphaco Probe. Born in Harlem in 1942, Bath faced numerous challenges as an African American woman aspiring to become a physician during a time when gender and racial biases were pervasive in the medical field.

Bath's journey began with a deep-rooted interest in medicine, stemming from her early years. She excelled academically, earning a medical degree from Howard University in 1968. Despite facing obstacles due to her gender and race, Bath specialized in ophthalmology, where she initiated significant advancements.

Her notable achievements include introducing a groundbreaking technique in cataract surgery, revolutionizing the approach to the procedure. However, Bath's most impactful contribution came in the form of the Laserphaco Probe, a device she developed to address the challenges associated with cataract surgery. This innovative tool utilized laser technology to efficiently and precisely remove cataracts, resulting in improved patient outcomes and transforming eye care on a global scale.

Despite encountering obstacles during the development of the Laserphaco Probe, Bath's resilience and determination prevailed. She not only overcame gender and racial barriers but also became a symbol of inspiration for future generations of medical professionals.

Beyond her inventions, Bath dedicated her career to advocating for health equality and access to medical care. Her influence extended to various medical innovations, leaving an enduring impact on the field.

In conclusion, Patricia Era Bath's contributions to medicine, particularly her invention of the Laserphaco Probe, have left an indelible mark on the history of ophthalmology. Her legacy is not only defined by the tangible advancements in medical technology but also by her unwavering commitment to breaking barriers and inspiring generations of medical professionals. The Laserphaco Probe stands as a testament to Bath's ingenuity, revolutionizing cataract surgery and enhancing the quality of life for countless individuals worldwide.

Wallace Hume Carothers (1896-1937)

Born on April 27, 1896, in Burlington, Iowa, Wallace Carothers was an American chemist and the leader of organic chemistry at DuPont and is credited with the invention of nylon.

He entered Capital City Commercial College in Des Moines in 1914 and graduated a year later in accountancy and secretarial administration.

After earning a bachelor’s degree in 1921 from the University of Illinois, Carothers went to the University of South Dakota, where he began his independent research at the same time he was a chemistry instructor.

After teaching for a year, Carothers returned to the University of Illinois in 1922 to work under Roger Adams. He earned a PhD from the University of Illinois in 1924 with specialty in organic chemistry. He was acclaimed as ‘one of the most brilliant students who had ever been awarded the doctor’s degree at Illinois’.

Carothers was then recruited by Harvard but after three semesters there DuPont offered him the task of organizing the company’s research in organic chemistry and especially polymerization.

Soon he had assembled the team of talented research scientists who would play a major part in the development of nylon. His first paper on polymerization appeared in the Journal of the American Chemical Society in 1929.

In 1936 Carothers was elected to the National Academy of Sciences, the first industrial organic chemist to receive this honor.

Thomas Alva Edison

He was called a ‘wizard’ because of his many important inventions. He created more than 1000 devices on his own or with others.

Thomas Alva Edison, known as ‘AI” as a child would be the last of the seven children born to his mother, Nancy. He was born on February 11, 1847 in Milan, Ohio.

He experienced hearing loss at an early age. He was an imaginative and curious child. He did poorly in school, though, perhaps because he could not hear his teacher. Edison’s formal education was limited to home schooling though he had set up his own chemical laboratory by the age of 10. Mathematics was his weakest subject, but he found chemistry to his liking.

In 1876, Edison built research laboratories at Menlo Park and West Orange, New Jersey. He later created companies that produced and sold his successful inventions.

Edison concentrated during the early 1870s on making advances in the telegraph, often improving on the work of earlier inventors.

Edison held 1069 patents on his inventions, which included such important innovations as the incandescent electric lamp and the phonographs.

He happened upon his only discovery in the realm of pure science accidentally when he noted what became known as the Edison effect, the emission of electrons a heated cathode.

At his death in October 18, 1931 Edison was celebrated as America’s most famous and prolific inventor but little recognized as a leader in the development of the industrial research and development laboratory.

Benjamin Franklin (January 17, 1706 – April 17, 1790)

Benjamin Franklin was a principal leader of the American Revolution. Before the war for independence Franklin earned fame as Philadelphia publisher and writer and world recognition as a scientist and inventor.

He was born in Boston. He was the 15th of 17th children. His father was a soap and candlemaker, who immigrated to United States from England.

At the age 12, Benjamin went to work as an apprentice to his older brother James who is a printer.

Benjamin Franklin

In 1723 Franklin moved to Philadelphia and worked as a printer. In 1724, he travelled to London, England to buy printing equipment. When he found himself stranded and without money, he went to work as a printer.

Benjamin was a great scientific thinker and inventor. He invented the Franklin stove, which was used to heat rooms, and a type of eyeglass called bifocals.  Benjamin also invented brighter street light, swim fins and library seats with built in stairs.

His experiments with electricity led to the invention of the lightning rod.

He served as deputy postmaster-general for the colonies and on the committee in the Second Continental Congress responsible for drafting the Declaration of Independence in 1776.
