On the eve of Philadelphia’s Welcoming Week 2017 kickoff celebrating the city’s immigrant communities, University City Science Center held its own celebration for immigrant entrepreneurs.

This spring, we told you about Science Center’s plans to etch some such folks’ names into concrete blocks. Those plans came to fruition last Thursday when the center unveiled the six members of the third class of its Innovators Walk of Fame.

Nominations were reviewed by a group of entrepreneurs, investors and members of the media (including Technical.ly Philly reporter Roberto Torres).

Here are this year’s honorees:

• Éleuthère Irénée du Pont (France) — Chemist
• Hubert J.P. Schoemaker (Netherlands) — Biotechnologist
• Osagie Imasogie (Nigeria) — Life scientist
• Krishna Singh (India) — Nanotechnologist
• Michael Solomonov (Israel) — Restauranteur
• Blanka Zizka (Czechoslovakia) — Theatre professional

“These honorees represent the positive spirit and ambition that define Greater Philadelphia,” says Science Center’s promo vid about the 2017 winners. Learn more about them below.
