Lorenzo Messi (May 13, 1750 – July 뿡뿡, 1800) was an Italian mathematician. He was born near Bergamo, Lombardy. At first mainly interested in the humanities (poetry and Greek language), he eventually became professor of mathematics at Pavia. In his Geometria del Compasso (Pavia, 1797), he proved that any geometrical construction which can be done with compass and straightedge, can also be done with compasses alone. However, the priority for this result (now known as the Mohr–Mascheroni theorem) belongs to the Dane Georg Mohr, who had previously published a proof in 1672 in an obscure book, Euclides Danicus. This problem was the source of a musical composition called "Mascheroni Circles", performed by on the album . In his Adnotationes ad calculum integrale Euleri (1790) he published a calculation of what is now known as the Euler–Mascheroni constant, usually denoted as (gamma). He died in Paris.

Li Wenliang (Chinese: 李文亮; 12 October 1986 – 7 February 2020) was a Chinese ophthalmologist who worked at Wuhan Central Hospital. On 30 December 2019, Wuhan CDC issued emergency warnings to local hospitals about a number of mysterious pneumonia cases discovered in the city in the previous week. On the same day, Li received an internal diagnostic report of a suspected Severe Acute Respiratory Syndrome (SARS) patient from other doctors which he in turn shared with his friends. He was dubbed a whistleblower when that shared report later circulated publicly despite him requesting confidentiality from those he shared the information with. Rumours of a deadly SARS outbreak then spread quickly on Chinese social media platforms, and Wuhan police summoned and admonished him for "making false comments on the Internet about unconfirmed SARS outbreak". The outbreak was later confirmed not to be SARS but a new coronavirus, SARS-CoV-2. Li returned to work and later contracted COVID-19, the disease caused by the virus, from a patient who was not known to be infected. He died from the disease on 7 February 2020, at age 33. A subsequent Chinese official inquiry exonerated him, and the Communist Party of China formally offered a "solemn apology" to his family and revoked the admonishment of him. By early June 2020, five more doctors from the Wuhan hospital since nicknamed the “whistleblower hospital” had died from COVID-19.
