Camp inspires students toward careers once beyond reach

Blind youths seek a future in science

Dave Wohlers leaned against the cold laboratory bench, gripping a white cane. He listened as the three blind girls across the bench struggled with their experiment.

"Oh, I dropped the wire," one girl said.

"I'll get it," replied another.

Her stool screeched across the tile floor of the Johns Hopkins University chemistry lab as she climbed down to grope for the wire.

The girls were building an electrolytic cell, a power source of the sort that might one day fuel ultra-green cars. Such technical projects are difficult, even for students with good eyes. But Wohlers showed no pity for the 20 or so blind students under his tutelage that morning.

His role as an instructor was to guide and inspire - not to coddle.

The experiment was part of Youth Slam 2007, a science camp sponsored this month by the Baltimore-based National Federation of the Blind that attracted about 200 blind students from around the country. It grew out of a larger initiative by the Jernigan Institute, a NFB program launched in 2004 to foster a culture of self-sufficiency in the blind community. Blind children are being pushed to pursue careers that even the most optimistic once thought beyond their grasp.

"The big thing is to inspire them to do more than they previously thought possible," said Mark Riccobono, executive director of the institute.

Bolstering the initiative are new electronic devices that act as a blind person's eyes by turning visual information into sound or Braille text.

IPod-sized translators can take photos of printed documents and read them out loud. Portable computers known as "notetakers" can store reams of information - novels, scientific data and personal reminders - then reproduce it instantly as lines of Braille. And talking instruments can tell blind scientists the color, temperature and weight of chemical compounds.

NFB officials say the combination of technology and hands-on lab experience will boost blind students' confidence. Wohlers hopes that will help them overcome hurdles similar to those that nearly kept him out of science. "If you can feed the thinking by doing it physically," he said, "somehow you have a recognition that `I can do this.'"

Such surety was hard won for Wohlers, who was completely blind by age 8, the result of a genetic condition that caused cancerous tumors to form on his retinas.

He first developed a keen interest in chemistry while attending a school for the blind in Vinton, Iowa. "I loved the competition in the classroom," he recalled. "And I loved the idea of synthesizing something new that nobody had made before." Aptitude tests also showed he might make a good scientist.

But Wohlers had never heard of a blind chemist and neither, it seemed, had anyone else. Back then, "blind scientist" sounded like a virtual impossibility.

When his high school guidance counselor told him it was too bad he couldn't go into chemistry, Wohlers didn't think to ask why he couldn't. "I just didn't know anybody who did that," he said. "If you were good, you were a teacher. If you were special good, maybe you were a lawyer. Otherwise, you were a piano tuner or broom maker, or some other manufacturing job."

In 1970, he entered the University of Iowa as an economics and business major, thinking it was a practical field for a blind man.

He soon discovered he had made a mistake. "I just couldn't stand reading that stuff, and I couldn't motivate myself," he said. "I realized that maybe I wasn't following my bliss."

After failing an economics exam, he switched to a double major in chemistry and mathematics despite his misgivings about science as a career. "There were no guarantees I could do the lab work," he said. "We didn't even have microcomputers then. I just had faith that someday there would be a solution, that the technology would catch up."

Other students acted as Wohlers' eyes in the laboratory. They handled the chemicals, mixed the various reagents and measured the products. Wolhers was the brains behind the operation, telling the volunteers what to do at each step.

He learned a lesson about science that would carry him through his career: The lead scientist doesn't have to do the laboratory grunt work. "It quickly became very apparent that chemistry is a cerebral sport," he said, "and not hand-to-hand combat."

Wolhers decided he would need to be the boss - managing the ideas, people and data, while delegating the bench work to sighted assistants. He could be intellectually immersed in the work, if not physically connected to research.

But not everyone was convinced a blind man could do science. Wolhers discovered this when he applied to the graduate program at Iowa State University's chemistry department.
