Alexander Alexandrovich Lubichev (April 5, 1890-August 31, 1972) was an entomologist, philosopher and mathematician in the former Soviet Union. Graduated from St. Petersburg National University, he has published more than 70 academic works, ranging from decentralized analysis, biological taxonomy to entomology. At the age of 26, he created an original "time statistics", which records the time spent on each event, makes monthly summaries and year-end summaries through statistics and analysis, in order to improve working methods and plan future affairs, so as to improve the efficiency of the use of time. During this period, he continuously improved this statistical method and used it for 56 years until his death.
