A big company makes things. 
A man named Herbert Dow started a big company. 
Later, the company made many new things. They made parts for fast cars. They even made plastic.
During a big war, the company was very busy. They made metal for planes. They also made fake rubber.
Now, the company is all over the world. It has workers in many lands. It helps make things for many shops.
Many things in your home come from this company.
Herbert Henry Dow started his company in 1897. 
As time went on, Dow made many new things. They made magnesium metal. This metal is very light. During World War II, Dow made magnesium for planes. They also made synthetic rubber. Synthetic rubber is a man-made version of natural rubber.
In the 1930s, Dow began making plastics. They made products like polystyrene. This is a type of plastic. They also made Saran Wrap. This is a clear wrap used in kitchens.
Today, Dow is a very large company. It is based in Midland, Michigan. It has workers in about 160 countries. Many of its products go to other businesses. This is why some call it the "chemical companies' chemical company." It helps make many things we use every day. 
The Dow Chemical Company is a huge business in the world of science. It is a large American corporation based in Midland, Michigan. In 2021, it was one of the three largest chemical producers on Earth. Most people do not buy its products directly at a store. Instead, it sells to other industries that make goods for us. This is why people call it the "chemical companies' chemical company." Today, it works in about 160 different countries.
The company started with one clever idea from a chemist. Herbert Henry Dow founded the business in 1897. He found a way to pull bromine out of salty water called brine. This brine was trapped deep underground in Michigan. At first, the company only sold bleach and potassium bromide. By 1902, they were making 72 tons of bleach every single day. 
As the years passed, the company grew by making many new things. This is called diversification, which means adding different products. During World War I, Dow made magnesium for bright flares. They also made chemicals for medicines and explosives. In the 1930s, they began making plastic resins. They made ethylcellulose in 1935 and polystyrene in 1937. 
World War II was a very busy time for the company. Dow built a huge plant in Freeport, Texas, to make magnesium from seawater. This plant was the largest site of its kind in the country. In 1942, Dow's plants made 84 percent of all magnesium in the United States. This metal was very important for making lightweight parts for airplanes. They also helped make synthetic rubber when natural rubber was hard to get. 
Many leaders helped Dow grow into a global name. Willard Dow was the son of the founder and led the company after 1930. Later, Leland Doan helped the company sell products directly to families. He helped expand sales from $200 million to $890 million. Ted Doan also led the company and helped it grow across the ocean. He helped set up offices on every continent to manage the business. 
The Dow Chemical Company is a massive American multinational corporation. Its headquarters are located in Midland, Michigan. In 2021, it ranked among the three largest chemical producers in the world. It operates as a subsidiary of Dow Inc., which is a holding company under Delaware law. The company has a presence in approximately 160 different countries. Currently, it employs about 36,000 people across the globe.
The company began with a single scientific breakthrough in 1897. Chemist Herbert Henry Dow founded the business in Midland, Michigan. He invented a new method to extract bromine from underground brine. Brine is a very salty water found deep beneath the earth. 

During World War I, Dow became a vital supplier for the United States. Because the U.S. previously imported many materials from Germany, Dow filled that need. The company produced magnesium for incendiary flares used in combat. It also manufactured monochlorobenzene and phenol for use in explosives. Additionally, Dow provided bromine for medicines and tear gas. By 1918, 90 percent of the company's total production supported the war effort. During this era, the company created the diamond logo that it still uses today.
The company's growth continued through the leadership of Willard Dow. He was the son of the founder and worked in every department. After his father died in 1930, Willard took over the company at age 33. Under his leadership, Dow invested heavily in research and development during the Great Depression. In the 1930s, the company entered the plastics market. They produced ethylcellulose in 1935 and polystyrene in 1937. These plastic resins eventually became one of the largest parts of the corporation's business.
World War II required Dow to expand its manufacturing capabilities rapidly. Between 1940 and 1941, Dow built its first plant in Freeport, Texas. This facility extracted magnesium from seawater rather than from underground brine. The Freeport site became the largest integrated chemical manufacturing site in the United States. 
After the war, the company underwent significant reorganization and expansion. Leland Doan became president in 1949 and focused on the growing consumer economy. As more Americans bought homes, the demand for household products increased. Doan expanded the sales force and began selling products directly to consumers. He oversaw a massive jump in sales from $200 million to $890 million. Later, Ted Doan became president and focused on international growth. He established headquarters on every continent to manage business in places like Germany, Italy, and New Zealand. 
Modern Dow is also shaped by complex corporate changes and historical responsibilities. In 2015, Dow and DuPont agreed to a massive corporate reorganization. They merged to form DowDuPont in 2017, then split into three separate companies. The materials science division became the new Dow Chemical Company in April 2019. The company's history also includes managing the Rocky Flats Plant near Denver, Colorado. From 1951 to 1975, Dow managed this facility which produced plutonium triggers for hydrogen bombs. This period included challenges with radioactive waste and fires, which the company had to manage under government oversight.
