On Dec. 31, 1879, Thomas Edison first demonstrated his electric incandescent lights for the public by illuminating some 100 bulbs in and around his laboratory in Menlo Park, New Jersey.

In 2019, the health commission in the central Chinese city of Wuhan announced that experts were investigating an outbreak of respiratory illness and that most of the victims had visited a seafood market in the city; the statement said 27 people had become ill with a strain of viral pneumonia, which would eventually be known as COVID-19.

In 2022, Pope Emeritus Benedict XVI, who had become the first pontiff in 600 years to resign as pope, died at age 95.
