{"name": "Isaac Barrow", "bio": {"type": "/type/text", "value": "Isaac Barrow was an English Christian theologian and mathematician who is generally given credit for his early role in the development of infinitesimal calculus; in particular, for the discovery of the fundamental theorem of calculus. His work centered on the properties of the tangent; Barrow was the first to calculate the tangents of the kappa curve. Isaac Newton was a student of Barrow's, and Newton went on to develop calculus in a modern form. The lunar crater Barrow is named after him.\r\n\r\nSource: Wikipedia"}, "personal_name": "Isaac Barrow", "death_date": "4 May 1677", "photos": [7401387], "birth_date": "October 1630", "type": {"key": "/type/author"}, "remote_ids": {"viaf": "56682703", "wikidata": "Q207718", "isni": "0000000083438438", "lc_naf": "n82070072", "project_gutenberg": "3430", "opac_sbn": "SBLV137247"}, "key": "/authors/OL1820237A", "latest_revision": 8, "revision": 8, "created": {"type": "/type/datetime", "value": "2008-04-01T03:28:50.625462"}, "last_modified": {"type": "/type/datetime", "value": "2025-07-31T19:03:03.279427"}}
