Who are the presidents of Harvard University in the United States? Especially from the beginning of the 20th century to the middle of the 20th century, there was a headmaster whose full name was "What Buddha is". In recent years, several presidents, such as Conant, Nathan Marsh Puxi, Derek Bok and the current president Lu, have made great efforts for the construction of Harvard University. On the one hand, they strive to improve the education quality of undergraduate and graduate students, and at the same time, they strive to play the prominent role of Harvard University as a research institution. Conant was a professor, dean and president of the Chemistry Department of Harvard University from19 to 1953. He implemented the off-campus special committee system at Harvard University to evaluate the qualifications and tenure of school teachers. He also created a general education program to provide all undergraduates with a wide range of research fields besides the main courses. From 1953 to 197 1, Puxi was the president. Under his auspices, Harvard University conducted the largest fundraising activity in the history of American higher education, raising 825 million dollars for Harvard. This activity has increased the salaries of Harvard university teachers, expanded the financial aid for students, established new professorships and enriched teaching equipment. Since 197 1, Bok has been the president. He seriously dealt with some major issues in higher education, including administration, educational opportunities for ethnic minorities and women, and technological transformation between academia and industry. President Bok also reorganized the management organization of Harvard University, and introduced modern management science and procedures into various graduate schools and departments of Harvard University. 199 1 year, Lu became the 26th president. As part of better coordinating the relationship between colleges and teachers, he launched a centralized academic plan for the whole school to determine the most important and priority parts of Harvard. In addition, Lu also emphasized the responsibilities of universities: excellent undergraduate education, the doors of universities are always open to people of different economic classes, and how research universities can adapt to the era of rapid information growth and serious financial constraints and meet challenges in a freely expressed society.
