In 1889 J. S. McMullen, age 55, pulled up stakes and went out West. He had spent most of his life in Michigan but perhaps he was enticed to start a new life by word of the rich natural resources of the Seattle area. McMullen brought his wife and four adult children, and the family became business leaders in the Fremont neighborhood.

In the early 1900s the McMullens had this office at the intersection of North 34th Street and Fremont Avenue. It served as a receiving station for their customers to be met and conducted to the larger Hay and Grain building nearby. Photo from the Fremont Colleague newspaper of 1904.
The McMullen family arrived at an opportune time, just before Seattle’s Great Fire of June 6, 1889 which resulted in an enormous demand for materials for rebuilding the city. The McMullens established a building materials company which supplied wood, brick, lime, plaster, cement and sand, and they had a fuel business of wood and coal used for heating homes. The company also sold hay, grain and poultry feed.
J.S. McMullen died in 1912 and his eldest son John E. McMullen took over the business. By that time, after more than twenty years in the community, the McMullens had become a dynasty in Fremont. John and his brother David led the company and several of their sons worked in the business.
The McMullen Company had a large complex between 34th to 35th Streets, Evanston to Phinney Avenues, with a large “Hay and Grain” sign visible on their building. In the larger photo below, look for the streetcar barn next to the McMullen building. Today the former car barn houses Theo Chocolate.

Before construction of the ship canal there was this ditch which had been created by hand-digging. Photo circa 1912, with the McMullen’s Hay and Grain building at right. Photo courtesy of MOHAI 83.10.6931.
The McMullens were vigorous advocates for the government’s ship canal route past Fremont because they knew it would enhance the business opportunities of the community. The ability to transport heavy items such as wood and coal via ship, to be unloaded at canalside, would be a great advantage to the McMullens and to other Fremont businesses.
The McMullens are an example of the emphasis of Fremont businessmen upon expansion of maritime and industrial use of the ship canal. In those days the main purpose of the ship canal was industrial including fishing boats. The pleasure boat traffic which we see travelling through the ship canal today, developed more slowly and was most in growth after the end of World War Two in the 1940s and 1950s.

Although the McMullen’s name is unfamiliar today, the McMullen’s large building with its “Hay and Grain” sign is an excellent orientation point in photos taken in 1911 to 1917 during the years of construction of the ship canal and the opening ceremony on July 4, 1917. The McMullen’s Hay and Grain building was at 460 Ewing Street (now called N. 34th Street) in the block between Evanston and Phinney Avenues.
The McMullens were in the block which today includes the Red Door Tavern at 3401 Evanston Avenue North, the Burke Building nearest to Phinney Avenue, and other commercial structures. In the 1916 photo below, the trolley car barn is visible. Today the old car barn building is the Theo Chocolate factory on the corner of 34th & Phinney.

Near the time of completion of the ship canal in 1916, we see the advantageous position of the McMullen’s Hay and Grain building, where products could be transported to the building by water. Photo courtesy of MOHAI 2006.7.1.

In 1894 Ross and Fremont were shown as place names with railroad stops. The ship canal had not yet been built but there was a creek called The Outlet from Lake Union, flowing westward.

Postscript: according to city directory listings, the McMullen Company closed down its operations in approximately 1932 during the depths of the economic crash called the Great Depression. The closure would have been due to the lack of building projects which were the customers of McMullen’s business. The McMullen property was later acquired by Wellington Coal, and then by the J.R. Burke company’s Industrial Center.
Fantastic, loved the photos and the history. What became of the family? Are any of them still in Seattle?
Your comment made me smile, because I also wonder about families although I did not trace the McMullens to the present day. John McMullen had five sons and some of them started other companies. With changes in the construction industry and factors like the economic depression of the 1930s, the Hay and Grain branch of the company went out of business.
