What were Henry ford's contribution's to life?

simple answer: his children, his creations, his kindness, the results of his hard work, the times he expressed gratitude and respect towards his (grand)parents, his wife, his mistresses.

if your question meant "Henry Ford the car manufacturer" the question raises another questions as to what you would define as "life" (as in: "the life of others, society, the world in which we live")

regarding most schoolbook examples of what Henry Ford as a person is supposed to have contributed to society is "mass-manufactoring of automobiles".

regarding what history writes that can be refined a bit into "making the price of an automobile achievable for a larger part of the (upper) working-class"

regarding "quality he has brought to life" that's a bit more difficult for the sake of introducing an oil and petrol guzzling object into the world, causing widespread death and disease for the sake of environmental polution and asbestos (for the sake of the brakeliners) and fume (for the sake of the benzene, toluene and xylnene) based cancers in modern day mankind, as well as many accidents due to faulty design and malfunction.

nowadays Henry Ford's contributions (like most of US-based manufatoring) are on the verge of collapse, especially in overseas markets where newer and better and more environmentally friendly cars are available from more progressive companies which invest in quality.
