(FORTUNE Magazine) – CHARLES E. JOHNSON, 34 FRANKLIN RESOURCES INC. With $44 billion in assets under this mutual fund company's wings, you might expect Johnson to sit back and let the average 0.5% fee the company charges to manage investments pay the rent. But Johnson, head of corporate development and oldest son of Chairman Charles B. Johnson, isn't content with the $253 million in revenues that the company pulled in last year from the 73 funds that Franklin runs. Johnson introduced some 25 of them. About 25% of American families invest in mutual funds, compared with around 6% in 1980, and the growth will probably slow. Says Johnson: ''The next arena is the rest of the world.'' First stops: Taiwan and London, where Franklin is opening offices to look for more investors.

DIANE W. UPRIGHT, 43 CHRISTIES INTERNATIONAL PLC In the world of art, this Upright is no slouch. She turned the Jan Krugier Gallery's by-appointment-only New York City office into a public showcase for museum-quality exhibits of 20th-century paintings and prints. As the new head of Christie's post-1945 art department in New York City, Upright must keep the gavel coming down even as the sizzling contemporary market starts to cool. ''We're looking for works of very high quality that haven't reached the market yet,'' she says. Upright hopes that the contacts she made as a Harvard art history associate professor and as the senior curator at the Modern Art Museum of Fort Worth will turn to her whenever they are thinking about selling paintings by the likes of Jackson Pollock and Mark Rothko.

MARC R. HANNAH, 33 SILICON GRAPHICS INC. ''By those naive expectations we're behind schedule.'' So says Hannah of his 1981 prediction that sales of the computer maker he co-founded that year would top $1 billion in the year ended June 1990. Instead, despite a 59% rise from 1989, they were only $420 million. Hannah, chief scientist for the Silicon Graphics division that makes lower-end workstations in the $10,000 to $30,000 price range, continues to think on a grand scale. He is developing less expensive computers that still deliver the powerful three-dimensional graphics capability he helped design, and expects to introduce a $5,000 model within two years. Says he: ''My goal is to broaden the market through lower prices.''
