Yakov Sannikov (Russian: Яков Санников) (1780, Ust-Yansk - no earlier than 1812) was a Russian merchant and explorer of the New Siberian Islands.

In 1800, Sannikov discovered and charted Stolbovoy Island, and in 1805 Faddeyevsky Island. In 1809-1810, he took part in the expedition led by Matvei Gedenschtrom. In 1810, Sannikov crossed the island of New Siberia and a year later explored Faddeyevsky Island. He also discovered Bunge Land.

He suggested that there was a vast land north of the Kotelny Island. This hypothetical island has become known as Sannikov Land.

A strait between Maly Lyakhovsky and Kotelny islands bears Sannikov's name.

Gad Elbaz (in Hebrew גד אלבז) (born August 20, 1980) is an Israeli singer of Sephardic origin. He is best known by his #1 hit; Halayla Zeh Hazman (Tonight Is The Time), and for being the son of mizrahi singer Benny Elbaz.

Elbaz started his singing career at the age of 13. His first duet was with his Grandfather, Yecheskel; who himself was a renowned Mizrahi singer, when they sang Aba, Otcha Ani Ohev (Father, I Love You). At the age of 7, Gad's family became religiously observant. The first and most famous song written by his father, and sung by the two of them after they became observant, was Lo Kashe Lachzor B'Tshuva (It Isn't Hard To Become Observant). The song was an instant hit, and touched the lives of thousands of non-observant Israeli families.

As a child, he recorded four records with his father, and later, five more on his own. He was 16 when he put out his first solo effort called (Light at the End of the Tunnel). In 2005, he released Meanings, which sold close to 100,000 copies in Israel alone. His songs feature catchy tunes, appealing to both the observant crowd as well as the non-observant. In 2006, he released another album named Kimat Shaket כמעת שקט, (Almost Quiet). A new disc called Bein HaTipot, (Between The Drops), was released in 2008 and co-produced by Rudy Perez, who has written several songs for Christina Aguilera. One song already playing on Israeli radio; Olam Shel Yeladim (World For The Children), has become a huge hit.
