Source-derived summary

Ivan (1962 – August 21, 2012) was a western lowland gorilla born in 1962 in what is now the Democratic Republic of the Congo. He was captured from the wild as a baby and brought to live with humans. For the first few years of his life he lived with his owners, but he soon grew too big for a human house and they moved him to a 14' x 14' concrete enclosure on display to the public at the B&I shopping center in Tacoma, Washington, where he spent the next 27 years of his life.

After local animal welfare organizations successfully campaigned for his release to a facility that could care for Ivan properly, in 1994, he was placed at Woodland Park Zoo in Seattle. Shortly after this, he was placed on permanent loan to Zoo Atlanta in Atlanta, Georgia. He spent his remaining years at Zoo Atlanta and died from complications during a medical procedure in August 2012.

Ivan's story was fictionalized in the 2012 book The One and Only Ivan by Katherine Applegate, which was adapted into a 2020 film of the same name.

Animal welfare controversy

In 1987, the animal rights group Progressive Animal Welfare Society (PAWS), upset at the conditions in which Ivan lived, began a campaign on his behalf. PAWS encouraged the community of Tacoma and other nearby cities to protest and to boycott the B&I shopping center. The community collected signatures, raised and donated money to PAWS, took out newspaper ads, and raised $30,000 to buy Ivan from the B&I shopping center to be re-homed within Seattle's Woodland Park Zoo.

Editorial summary

This brief starts where responsible research should: with the source description of “Ivan (gorilla)” as gorilla. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1962, 2012, 1994, 2020—that can be checked directly. The linked authority record independently contributes the date 1962. The account is most persuasive where Ivan and gorilla can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as gorilla. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q17146717. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1962, 2012, 1994 and 2020.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
