Ignominiously

A window opened above the shop, and a frowsty-looking man, yellow-pale, was quickly and nervously hauling in the national flag. There were shouts of derision and mockery—a great overtone of acrid derision—the flag and its owner ignominiously disappeared.

He laughed rather ruefully, as he described how he had discovered a very rare species of fern in an inaccessible place, and in his efforts to obtain it had lost his footing, and slipped ignominiously into a neighbouring pond.

But his [James D. Watson's] official career there ended ignominiously in 2007 after he ignited an uproar by suggesting, in an interview with The Sunday Times in London, that Black people, over all, were not as intelligent as white people.
