Nikola Tesla’s mother, Djuka, though always described accurately
enough as an illiterate, but an extraordinarily gifted woman, has
been, at various times, and often enough, referred to, and spoken
of, as a Croat. There was a tendency in the former Yugoslavia to
look for unifying factors which would help bring its different
nationalities closer together; thus, a certain political task fell
on the Tesla mother and son, and Djuka became a Croat, and in some
unscrupulous quarters is still so regarded, the demise of the former
country, and the destruction of Tesla’s birthplace in 1941, and
fires, vandalism, desecration, and blowing up of Tesla’s monuments
again in 1992, notwithstanding.

Georgina-Djuka Tesla was born in Tomingaj (“Tomo’s wood enclosure”-
so named after her great-grandfather), the daughter of Nikola Mandic
(1800 -1863), a Serbian Orthodox priest in Gracac, and the grandfather
of Toma Budisavljevic (1777 – 1840), another priest, who was also a
military commander, a cartwright, and a fine bookbinder. She was the
oldest of eight children. Her mother became blind when Djuka was 16
yars old, and so it fell to her to look after her seven yonger siblings,
until her marriage to Milutin in 1847.

Djuka and Milutin Tesla had five children: Dane (1848 – 63),
Angelina (married name Trbojevic), Milka (married name Glumicic),
Nikola (1856 – 1943), and Marica (married name Kosanovic). All three
girls married Serbian Orthodox priests. Nikola, the fourth child, was
born on June 28, according to the Julian calendar, or July 10, according
to the modern calendar. He was born “at the stroke of midnight” during a
summer storm and lightning. The village midwife, afraid of storms, said,
“He’ll be a child of the storm,” to which the mother replied,
“No, of light.”

Nikola’s Baptism Certificate, in the Nikola Tesla Museum in Belgrade,
states that he was born on June 28, and christened the very next day, by
the Serbian priest from nearby Gospic, Toma Oklobdzija; the godfather was
Jovan Drenovac, a Captain in the Krajina army, also of Gospic. This
baptism, within twenty-four hours of birth, with the priest coming
to the house, instead of the child being taken to the church, is
believed to have been due to the seeming poor health of the infant.
According to Tesla’s autobiography My Inventions, he regarded his mother
as a “woman of genius, especially gifted with a sense of intuition”,
and credited her with whatever inventiveness and destiny in life he
posessed.

Read up on our history, we have some pretty amazing people and story’s originating from here, like the story of the priest who single-handedly drove off invaders of the island Korcula”[/quote]

Think again. Georgina-Djuka Tesla was born in Tomingaj (“Tomo’s wood enclosure”- so named after her great-grandfather), the daughter of Nikola Mandic (1800 -1863), a Serbian Orthodox priest in Gracac, and the grandfather of Toma Budisavljevic (1777 – 1840), another priest, who was also a military commander, a Cartwright, and a fine bookbinder. She was the oldest of eight children. Her mother became blind when Djuka was 16 years old, and so it fell to her to look after her seven younger siblings, until her marriage to Milutin in 1847. Milutin Tesla was born in Raduc, county Medak, Lika, on February 19 (OS), 1819. The Serbs came to Raduc from around Knin in the 1690s, having arrived there from western Serbia, via Herzegovina. The name Tesla denotes either a trade, as tesla is Serbian for adze- a small axe with a blade at right angles to the handle – or a physical characteristic, such as protruding teeth, prevalent in the Tesla family. The name Tesla is also found in Ukraine. None of this even suggests he was Croatian, other then that he was living on what is now Croatian land, but what was then Austrian land. So he was as much Croatian as he was Austrian or American, all countries which royally screwed him at some point in his life.

The Colorado Springs museum closed in December 1998, but the coil is in the possession of Bill Wysock of Tesla Technology Research. Wysock restored the coil after original owner Dick Aurandt’s death, donated it to the International Tesla Society for the museum in 1992 and received it back after the museum closed. Most of the museum’s assets were sold at auction.
