Culpeper's work emphasized the use of native plants and folk remedies, challenging the medical establishment of his day. He also advocated for affordable healthcare for the poor and was associated with the radical Leveller movement. His passion for botanical illustration led him to document hundreds of plant species with detailed descriptions. Although he died young in 1654, Culpeper's herbal remains in print and continues to influence herbal medicine practitioners.

Arie de Jong was born in 1865 in the Netherlands and dedicated his career to language studies. He became a leading proponent of Ido, an international auxiliary language derived from Esperanto. De Jong authored the first complete Ido grammar and a detailed dictionary that shaped the language’s development. His scholarly approach and educational materials helped the Ido movement grow in the early 20th century. He remained active in linguistic circles until his death in 1957, leaving a lasting legacy in constructed language history.

D. T. Suzuki was born in 1870 in Kanazawa, Japan, and became one of the most influential interpreters of Zen Buddhism. He wrote extensively in English, publishing works like 'An Introduction to Zen Buddhism' that reached Western audiences from the early 20th century. Suzuki’s collaboration with Western scholars and artists helped spark global interest in Eastern philosophy. He held academic posts in Japan and lectured at American universities. Suzuki’s clear, accessible writing bridged cultural divides and shaped Western perceptions of Zen practice.

Max Gerson (1881–1959) was a German-born physician who pioneered an alternative dietary-based therapy, later known as the Gerson Therapy. Trained in Germany, he immigrated to the United States in the 1930s to escape Nazi persecution. Gerson developed his treatment protocol based on nutrition, detoxification, and enzyme-rich juices to bolster the body's self-healing. He applied his therapy to patients with tuberculosis and cancer, reporting cases of remission. Despite controversy and lack of acceptance by mainstream medicine, his approach gained a following among alternative health communities. He authored several books detailing his theories and case studies. Gerson's methods remain one of the most well-known forms of nutritional therapy for chronic diseases. His legacy is marked by ongoing debates over the role of diet in medical treatment.

George Ohsawa, born Yukikazu Sakurazawa and later known by his pseudonym, was a Japanese philosopher and academic. He founded the modern macrobiotic diet, emphasizing whole grains, vegetables, and balance. Ohsawa authored numerous books introducing Eastern philosophy, Zen, and natural hygiene to Western audiences. He traveled extensively, giving lectures and establishing macrobiotic schools across Japan and Europe. In 1959, he founded the East-West Philosophy Institute in Paris to promote intercultural understanding. His teachings influenced alternative health movements and holistic nutrition in the 20th century.

Isabel Briggs Myers worked with her mother Katherine Cook Briggs to design the MBTI based on Carl Jung’s personality theories. First published in 1943, the Myers-Briggs Type Indicator assesses individuals across four dichotomies to define 16 personality types. Briggs Myers aimed to help women in wartime workforce discover suitable careers matching their personalities. Her instrument gained popularity in education, business, and counseling, influencing personnel selection and personal development. She refined the MBTI over decades, authoring manuals and training programs to ensure its reliability and validity. Despite controversies over its psychometric properties, the MBTI remains one of the most widely administered psychological tests globally. Briggs Myers’s work contributed significantly to the popular understanding of personality and typology.

Pascual Jordan worked alongside Max Born and Werner Heisenberg to formulate the early mathematical framework of quantum mechanics. In 1925, he co-authored the groundbreaking ‘Dreimännerarbeit’ paper introducing matrix mechanics. He introduced Jordan algebras, providing algebraic structures underpinning quantum theory. Despite significant scientific contributions, his career was marred by political affiliation with the Nazi party. After World War II, Jordan was banned from academia but later resumed research, focusing on quantum field theory and gravitation. He published influential works on quantum electrodynamics and maintained correspondence with leading physicists. Jordan’s theoretical innovations continue to impact modern physics and mathematics.
