And while today it is known as a symbol of liberty for millions of refugees and exiles, initially the famous sonnet by Lazarus in the voice of the statue asking for "your tired, your poor, your huddled masses yearning to breathe free" did not appear on the statue. It was not until 1903 that "The New Colossus" was placed on the pedestal.

The statue's webcams will offer views from the torch that have been unavailable to the public since 1916, said Stephen A. Briganti, the president of the Statue of Liberty-Ellis Island Foundation Inc.

Through the webcams, Internet users around the world will have four views, including a high-quality, 180-degree stitched panorama of the harbor with stunning views of Ellis and Governors islands. They will be able to watch as ships go by Liberty Island and observe as the Freedom Tower at the World Trade Center goes up floor-by-floor in lower Manhattan. They can get a fish-eye look at the torch itself as it glows in the night.

The five cameras, which will be on 24 hours, seven days a week, were donated to the National Park Service by Earthcam Inc., a New Jersey-based company that manages webcams around the world.

The cameras put viewers on the balcony of the torch and high above the crown, said Brian Cury, the founder of Earthcam.

"This is not your dad's picture of the Statue of Liberty," he said. "This is not a view from a tourist helicopter. This is unique."

Friday's ceremony also will be marked by a water flotilla, actress Sigourney Weaver reading Lazarus' poem and a naturalization ceremony for 125 candidates for citizenship representing over 40 countries.

The public is invited to attend the ceremony, with ferry service available between Manhattan and Liberty Island. The interior of the statue — from the pedestal down to the museum base — will close after the 125th anniversary celebration for up to a year so that stairwells, elevators and mechanical systems can be upgraded. The park itself will remain open to visitors.

Lazarus is the subject of a new exhibit at the Museum of Jewish Heritage in lower Manhattan, which has views of Lady Liberty. It's to open Wednesday to coincide with the anniversary of the statue's dedication.

Curator Melissa Martens said Lazarus was born into the fourth generation of a Jewish family in New York prominent since colonial times. "They were some of the early people to articulate the Jewish experience in dialogue with the challenges of freedom and religious liberty," she said.

Featuring over 83 original objects from 27 institutions and individuals, "Poet of Exiles" is the first full-fledged artifact exhibit at a major museum to robustly explore the life of Lazarus, from her work as an advocate for immigrants fleeing the Russian pogroms of the early 1880s to her pioneering support for a Jewish homeland.

Lazarus died in 1887 at age 38 from Hodgkin's disease, never having known her poem would be united with the Statue of Liberty.
