Muhammad ibn Ismail al-Bukhari was born in 810 in the region of Bukhara (present-day Uzbekistan). He dedicated his life to collecting, verifying, and organizing the sayings of the Prophet Muhammad. Over 16 years, he traveled across Khorasan, Iraq, Hejaz, and Egypt to meet with over a thousand teachers. His Sahih al-Bukhari, compiled around 846, is considered the most authentic hadith collection in Sunni Islam. He applied meticulous criteria to determine the reliability of narrators and chain of transmission. Al-Bukhari’s work set a gold standard for hadith methodology and remains indispensable for Islamic scholarship. He passed away on September 1, 870, leaving a legacy that continues to guide religious studies worldwide.

Born in 1529, Pasquier studied law at Toulouse and became a prominent jurist in the Parlement of Paris. He authored 'Recherches de la France,' one of the first works of national history in Europe. His writings combined legal expertise with humanist scholarship, influencing French historiography. Pasquier also wrote poetry and essays that reflected the cultural debates of the Renaissance. He mentored younger scholars and contributed to the intellectual life of 16th-century France. He died in 1615, leaving a legacy as a pioneering historian and legal thinker.

Born in 1588, Mersenne joined the Minim religious order while pursuing studies in mathematics and theology. He collated and disseminated scientific ideas through extensive correspondence with figures like Descartes and Galileo. Mersenne’s study of prime numbers led to the concept of Mersenne primes, still studied in number theory. He authored 'Harmonie Universelle,' a seminal work on music theory and acoustics. As a theologian and philosopher, he sought to reconcile faith with emerging scientific discoveries. He died in 1648, leaving a legacy as a facilitator of the scientific revolution.

Born in 1854, Samu Pecz studied architecture at the Technical University of Budapest. He designed notable structures including the main building of the Budapest University of Technology and Economics and several historicist churches. Pecz's style blended Gothic Revival elements with emerging modernist sensibilities. As a professor at his alma mater, he influenced a generation of Hungarian architects through both his teaching and published works. He also wrote on architectural theory and urban planning, advocating for thoughtful integration of buildings within the cityscape. Pecz's buildings remain prominent features of Budapest's architectural heritage.

Born in 1878, Peeter Põld was a pioneer of modern Estonian education and journalism. He studied at the University of Tartu and later became a schoolteacher and publisher of educational journals. After Estonia declared independence in 1918, Põld was appointed as its first Minister of Education, laying the foundations for a national school system. He promoted Estonian-language instruction and comprehensive teacher training programs. In addition to his political work, he authored textbooks and conducted research on pedagogical methods. His contributions helped shape an education system that remains a cornerstone of Estonian society.

Born in Millis, Massachusetts in 1900, Haskell Curry earned his Ph.D. from Harvard University in 1929. He served on the faculties of Pennsylvania State University and other institutions, conducting pioneering research in combinatory logic. Curry's work on the Curry-Howard correspondence and combinatory calculi provided key insights linking logic and computer science. His theoretical contributions directly influenced the development of functional programming languages, including the language Haskell named in his honor. He authored several influential papers and books that shaped modern logic and computation. Curry remained academically active until his death in 1982, leaving a lasting legacy in mathematical logic.

Born in San Francisco in 1911, Luis Walter Alvarez earned his Ph.D. at the University of Chicago under Nobel laureate Arthur Compton. During World War II, he contributed to the development of microwave radar at MIT's Radiation Laboratory, enhancing Allied detection capabilities. After the war, Alvarez joined the faculty at the University of California, Berkeley, where he invented the hydrogen bubble chamber to study subatomic particles. His discoveries of numerous resonant states in particle physics earned him the 1968 Nobel Prize in Physics. In collaboration with his son, geologist Walter Alvarez, he proposed the asteroid impact theory for the Cretaceous–Paleogene extinction event. Alvarez authored several books and was awarded the National Medal of Science before his death in 1988.

A. Bartlett Giamatti (January 3, 1938 – September 1, 1989) was an American academic and baseball executive. He became the youngest president of Yale University in 1978 and oversaw expansion of its academic programs. In 1989, he was appointed the seventh Commissioner of Major League Baseball. During his brief tenure, he notably dealt with the Pete Rose gambling scandal. Giamatti's rulings emphasized integrity in professional sports. He died unexpectedly of a heart attack at age 51 while in office. His contributions reshaped collegiate and professional athletics.

Tadeusz Sendzimir (1894 – September 1, 1989) was a Polish-American engineer and inventor whose innovations transformed steel production. He invented the Sendzimir mill, a compact and efficient rolling mill design that enabled thinner and stronger metal sheets. His work led to over 160 patents across metallurgy and mechanical engineering. Sendzimir’s technologies were implemented by steel mills worldwide, boosting industrial productivity. He received numerous honors for his achievements, including induction into the National Inventors Hall of Fame. His methods remain fundamental to modern metalworking processes.

Edwin O. Reischauer (1910 – September 1, 1990) was an American historian and diplomat specializing in East Asian studies. As a Harvard University professor, he published influential works on Japanese culture and history. Appointed by President Kennedy, he served as U.S. Ambassador to Japan from 1961 to 1966. During his tenure, he promoted closer cooperation between the United States and Japan amid Cold War tensions. Reischauer received the Order of the Rising Sun from the Japanese government. His clear writing and policymaking insights shaped U.S. foreign policy in Asia. He continued to teach and write until his death.

W. Richard Stevens (1951 – September 1, 1999) was a computer scientist and technical author whose writings defined network programming. His books, including 'UNIX Network Programming,' 'TCP/IP Illustrated,' and 'Advanced Programming in the UNIX Environment,' became staple references for developers. Stevens’s clear, example-driven style helped demystify complex protocols. He held a Ph.D. in computer science and consulted for technology companies worldwide. His work contributed significantly to the understanding and implementation of internet technologies. Stevens’s books remain essential reading for network and systems programmers.

Warren Mitofsky revolutionized political polling with his creation of the modern exit poll technique. He founded Mitofsky International and consulted for major media organizations and governments worldwide. Mitofsky first implemented systematic exit polling during the 1967 New Jersey gubernatorial election. His methods provided critical insights into voter behavior and have become a staple in election coverage. He also contributed to research on survey methodology, improving accuracy and reducing bias in opinion polls.
