| Additional information |
Nicolae Donici (1874–1956) was a Moldovan-born astronomer who founded the Donici Astrophysical Observatory at his estate in Dubăsari in 1908 — one of the earliest purpose-built private observatories in the Russian Empire, equipped at his own expense with instruments sourced from Western Europe. He made significant contributions to solar corona research, particularly through observations conducted during total solar eclipses across multiple expeditions in the early twentieth century.
The observatory itself was dismantled under Soviet administration after World War II.
