What was the first industry established by settlers in seattle?

White settlers came to the Seattle area in 1851, establishing a townsite they first called New York, and then, adding a word from the Chinook jargon meaning "by-and-by," New York-Alki. They soon moved a short distance across Elliott Bay to what is now the historic Pioneer Square district, where a protected deep-water harbor was available. This village was soon named Seattle, honoring a Duwamish Indian leader named Sealth who had befriended the settlers.
