Geography
This island is 45 km long, stretching from the NW to the SE. Its area is 448 km² and it is almost completely unglacierized. The highest point on Ziegler Island is 554 m. Cape Brice (мыс Брайса) marks the northwestern corner. Cape Washington (мыс Вашингтона) lies in the very east. The southernmost point is called Cape Belousov (мыс Белоусова).

Adjacent islands
Ziegler Island is part of the Zichy Land subgroup of the Franz Josef Archipelago. Booth Channel (пролив Бута) separates it from Payer Island and Greely Island to the north. Salisbury Island lies across Rhodes Channel (пролив Родса) to the south. To the east, beyond Collinson Channel (пролив Коллинсона), is Wiener Neustadt Island.

The highest point of the unglacierized island is 393 m. Ugol'noy Kopi is separated from Ziegler Island by about 600 m.

History
The southeast of Ziegler Island was sighted by the Austro-Hungarian North Pole expedition in 1874. Co-expedition leader Julius Payer presumed that it was connected to the other islands of Zichy Land.

The exploration done by the 1894-1897 Jackson-Harmsworth expedition reduced the supposed landmass of Zichy Land appearing on the maps considerably. Jackson sighted Ziegler Island from the northwest and named Cape Brice after Arthur Montefiore Brice, the expedition's secretary.

The 1901-1902 Baldwin-Ziegler Polar Expedition on ships America, Frithjof, and Belgica named Cape Washington and were the first to set foot on the island. In May 1902 Evelyn Briggs Baldwin ascertained that Ziegler Island was a distinct entity. He named the island after the expedition sponsor, New York businessman William Ziegler. Ziegler was also the sponsor behind the 1903–1905 Ziegler-Fiala Polar Expedition that improved upon Baldwin's map.

The Austrian observing site Payer–Weyprecht (probably 81.1°N, 56.18333°W) was established around the start of the 20th century on this island.
