No, Betty Crocker isn't a real person. The company was founded by Dr. August Oetker in 1891. The first product developed by Dr. Oetker was "Bakin", a premeasuremed amount of baking powder that, when mixed with 500g of flour and other ingredients, produced a cake. http://tinyurl.com/3br3en Betty Crocker, an invented persona and mascot, is a brand name and trademark of American food company General Mills. The name was first developed by the Washburn Crosby Company in 1921 as a way to give a personalized response to consumer product questions. http://tinyurl.com/2m92xe

1) "Dr. Oetker is a German company that produces baking powder, cake mixes, frozen pizza and pudding. Also included in the portfolio: a successful maritime freight business, a bank, a publishing company, an insurance outfit and a brewery." "The company was founded by Dr. August Oetker in 1891. The first product developed by Dr. Oetker was "Bakin", a premeasuremed amount of baking powder that, when mixed with 500g of flour and other ingredients, produced a cake."

The name was first developed by the Washburn Crosby Company in 1921 as a way to give a personalized response to consumer product questions." "Company executives chose the name "Betty" because it seemed warm and friendly to them. The surname "Crocker" was borrowed from retired executive William H. Crocker. At first "Betty Crocker" was merely used as a fictitious personal signature to replies to customers asking advice. Then, in 1924, Betty Crocker found a voice with the debut of the daytime radio broadcast known as The Betty Crocker Cooking School of the Air. The show was voiced and scripted for two decades by Marjorie Husted, and went on to run through to 1953 (and was a big hit in its time)" Source and further information: http://en.wikipedia.org/wiki/Betty_Crocker 3) So both of them are band names in the food industry (backing), but Dr. Oetker was the real inventor of a backing powder and Betty Crocker was always a fictional character.
