Seattle Open Invitational
golf tournament formerly on the PGA Tour

The Seattle Open Invitational was a professional golf tournament on the PGA Tour in the northwest United States, in the greater Seattle area. It was played eight times over three decades under five names at three locations.
History
The first Seattle Open was held 90 years ago in 1936 at Inglewood Golf Club in Kenmore in early August. Macdonald Smith won an 18-hole playoff with a course record 65 (–8), six strokes ahead of runner-up Ralph Guldahl, who won the next two U.S Opens (1937, 1938) and the Masters in 1939. The next Seattle Open was played nine years later in October 1945 at Broadmoor Golf Club in Seattle and won by Byron Nelson, with a world record 259 (–21) and a victory margin of 13 strokes. He won a record eighteen tournaments in 1945, including eleven consecutive.
Sixteen years later, the tour returned to Seattle in 1961 at Broadmoor in mid-September with the Greater Seattle Open Invitational. Dave Marr won in a sudden-death playoff, over Bob Rosburg and Jacky Cupit; Marr shot a final round 63 (–7) and birdied the first extra hole to win. In 1962, it was renamed the Seattle World's Fair Open Invitational as part of the region's celebration of the 1962 Seattle World's Fair. The victor by two strokes was a 22-year-old rookie from Ohio named Jack Nicklaus.
This brief starts where responsible research should: with the source description of “Seattle Open Invitational” as golf tournament formerly on the PGA Tour. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as golf tournament formerly on the PGA Tour. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 28, 2026. The linked authority identifier is Q7442145. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1936, 1937, 1938 and 1939.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
