John D. Ingalls was born in London, England, where he attended grammar school, leaving England just before the London Blitz in WWII. He grew up in Sarasota, Florida, and attended Berklee College of Music in Boston. He became a professional musician and was well known and respected by his professional associates. Ingalls graduated from Boston College (Magna Cum Laude) in 1959 and from Boston University in 1970 where he obtained a Master of Education degree in Adult Learning and Applied Behavioral Science. At BU he worked closely with Malcolm S. Knowles, esteemed author and Adult Learning expert.
After spending 15 years as an human resources executive in Boston area companies, Ingalls founded his own consulting firm and successfully completed many long-term consulting assignments involving human development in major corporations, government agencies and health care organizations.
