Source-derived summary

Major General Count Albert-Marie Edmond Guérisse (5 April 1911 – 26 March 1989) was a Belgian Resistance member who organized French and Belgian escape routes for downed Allied pilots during World War II under the alias of Patrick Albert "Pat" O'Leary, purportedly the name of a peace-time Canadian friend. His escape line was dubbed the Pat O'Leary Line.

Biography

Guérisse was born in Brussels, and qualified in medicine at the Université Libre de Bruxelles before joining the Belgian Army. Guérisse was Médecin-Capitaine with a Belgian cavalry regiment during their eighteen-day campaign in May 1940. He managed to escape to England through Dunkirk. At Gibraltar, he joined the crew of a former French merchant ship, Le Rhin, which was later renamed HMS Fidelity and served in the Mediterranean on clandestine missions. He secured entry into the British Royal Navy and was commissioned as Lieutenant Commander Patrick Albert O'Leary RNVR of French-Canadian origin. The "Canadian" identity attempted to explain his not-quite British accent in English, and his not-quite French accent in French, in order to protect his family in occupied Belgium if he was captured. He had a six-week undercover training session with Naval Intelligence. Until April 1941, he was serving mainly as a conducting officer, escorting agents ashore in small boats through the surf, whilst the large vessel lay some distance offshore.

Editorial summary

Begin with the source’s own compact description: “Albert Guérisse” is resistance fighter 40-45 (GB) - Belgian medical officer. The dossier treats that line as a proposition to test through Albert, Guérisse and Resistance, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1911, 1989, 1940, 1941—that can be checked directly. The authority record carries competing date values—1911-04-05, 1911—which should remain separate until their references and qualifiers are resolved. For this dossier, Albert, Guérisse and Resistance is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “resistance fighter 40-45 (GB) - Belgian medical officer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

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 Aug 10, 2026. The linked authority identifier is Q2744035. VIAF identifies the subject as 309894005. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
