Not just long-forgotten, many VPs were barely known even during their terms, never called to greatness, with no discernable effect on the present day.
An exception is John Tyler, who was William Henry Harrison's running mate and became VP in 1841. There are a lot of odd facts in his career, and I'll save the most amazing fact till the last.
Tyler took little interest in the Veep job until he received word a month after the March inauguration that Harrison had died of pneumonia. Then he rushed to Washington.
Although the Constitution as it stood in 1841 was unclear on the details of succession in the event of the President's death (some felt that the VP could be nothing more than a caretaker for the remainder of the term), Tyler announced to Congress that he was indeed the President and moved into the White House. He took a second oath of office to clinch the claim.
Congress went along with the bold move, though there was no firm legal basis for calling him "President Tyler" until the 25th Amendment passed in 1967. Some wags referred to him as His Accidency.
What's more, Tyler had no vice president at all during his term, which lasted almost four years. The Executive has been VP-less seventeen times.

While in office Tyler estranged himself from his Whig Party and dropped out of the 1844 election, leaving office in March 1845.
His term could have ended a year before that. On February 28, 1844, he was enjoying a short river cruise aboard the new steam-powered frigate USS Princeton, along with dozens of dignitaries. The captain wanted to show off a new, powerful 12-inch cannon dubbed the Peacemaker. It exploded the third time it was test-fired for the VIP entourage. Tyler had been coming from below to see the cannon, and would have been in fatal range in another few seconds. As it was, the blast killed two members of his cabinet (lithograph by N. Currier)
Leading to the most peculiar fact: it's been 230 years from John Tyler's birth, but he has a living grandchild named Harrison Ruffin Tyler. This seems impossible, but it's true: Tyler married a much younger woman and fathered seven children with her, and son Lyon Gardiner Tyler also had children very late in life.
