Went to Sunday school. I stayed for church. Ollie was over. Played cards in evening.

September 30, 1934: Babe Ruth's final game as a New York Yankee. He batted 0 for 3. From New York, he went to the Boston Braves. He played in his last Major League game in Philadelphia on May 30, 1935, when he left the field with a hurt knee.

Straightened up the house. Martha and Mary Jane from Topeka came down. I went to town with them. Later, Myrtle came down. We took them over to their brother-in-law's.

Inventor: Harry R. Drackett
Launch Year: 1933

When Windex was invented as a car windshield cleaner in 1933 by Harry R. Drackett, it was
essentially 100% solvent, and as a flammable product, it had to be sold in metal cans. When
 modern surfactants were  introduced after World War II, the product was reformulated.

The Sam Wise patent #3,463,735 lists several example formulae, one of which is 4.0%
isopropyl alcohol (a highly volatile solvent) 1% ethylene glycol monobutyl ether
(a less volatile solvent), 0.1% sodium lauryl sulfate (a surfactant), 0.01% tetrasodium
pyrophosphate (a water softener), 0.05% of 28% ammonia, 1% of a dye solution, and 0.01%
perfume. This formula was not only significantly less expensive to manufacture, but allowed 
the product to be packaged in glass bottles and dispensed with a plastic sprayer.

The product was recently reformulated by its current manufacturer, S. C. Johnson Company,
with more environmentally desirable solvents.
