Who Should Be Among This Year's Picks for the Time 100?

To help make the selection, TIME asked earlier honorees whom they would select as the world's most influential people. The final installment:

JOHN ELDERFIELD

He is the chief curator of New York City's Museum of Modern Art

Bob Dylan, the greatest contemporary rock musician. He just keeps performing, at tiny places where people can afford to get in and hear him. There has been even more exposure to him through his book and the film about his life. What he stood for when he came to prominence is as relevant now. At his age, as he sings against the war, a chill goes through the audience. They know what he's talking about.

MITCHELL BAKER

With the title "chief lizard wrangler," she oversees the organization that developed Mozilla and the Firefox Web browser

I nominate Mukhtaran Bibi, the Pakistani woman also known as Mukhtar Mai, who was gang-raped as punishment for her brother's walking with a girl from a higher tribal group. She deserves to be honored for her courage and determination in fighting the system and for continuing to shed light on the problems of rape and illiteracy, despite the personal danger and costs.

AMY DOMINI

She runs a socially responsible mutual fund and wrote the book Ethical Investing

I would like to nominate Carlo Petrini, who was the founder of the slow-food movement. That organized rebuke of fast-food culture began in Italy and has since grown into an international force for pleasant living, sustainable agriculture, heritage animal protection and even cultural survival. It is still largely under the mainstream's radar, but its trade shows in Torino, Italy, regularly attract 140,000 people.

PAUL RIDKER

He is the director of the Center for Cardiovascular Disease Prevention

I nominate Jeffrey Sachs, director of the Earth Institute at Columbia University. He is an economist who has committed himself to the concept of economic development as a method of reducing poverty-related disease. His latest initiative, Breaking the Bottlenecks, aims to cut through the red tape that slows the creation and distribution of malaria-prevention and -treatment programs in 10 African countries.
