- Janusz Korczak (Wikipedia)
Janusz Korczak, the pen name of Henryk Goldszmit (22 July 1878 or 1879 – 7 August 1942), was a Polish Jewish pediatrician, educator, children’s author and pedagogue known as Pan Doktor (“Mr. Doctor”) or Stary Doktor (“Old Doctor”). He was an early children’s rights advocate, in 1919 drafting a children’s constitution. ¶ After spending many years working as a principal of an orphanage in Warsaw, he refused sanctuary repeatedly and stayed with his orphans when the entire population of the institution was sent from the ghetto to the Treblinka extermination camp during the Grossaktion Warschau of 1942.
- Domain (biology) (Wikipedia)
In biological taxonomy, a domain (/dəˈmeɪn/ or /doʊˈmeɪn/) (Latin: regio), also dominion, superkingdom, realm, or empire, is the highest taxonomic rank of all organisms taken together. It was introduced in the three-domain system of taxonomy devised by Carl Woese, Otto Kandler and Mark Wheelis in 1990.
