Random London Fact of the Day
The RMS Titanic sank in the North Atlantic Ocean 101 years ago today after colliding with an iceberg, resulting in the deaths of over 1,500 people. Monuments and memorials associated with the event exist all over the world, so it's no surprise that there are a few in London. A small and slightly odd Titanic Memorial Garden exists at the Royal Observatory, Greenwich, which was opened in 1995 by Edith Haisman — at the time one of the oldest living survivors of the tragedy. You can also find a plaque hanging inside the Institute of Marine Engineers headquarters in Aldgate, to commemorate the 35 engineers who lost their lives. The Chadwell Heath Wetherspoon pub is named after Eva Hart, a survivor of the disaster who lived locally until her death in 1996. Finally, a plaque resides in the Royal Albert Hall dedicated to the musicians on board the ship, who were subsequently hailed as heroes for keeping playing as the ship sank, in order to provide relief and calm other passengers.
Good Cause of the Day
A bunch of regulars at The Watermans Arms Pub in Brentford, plus the landlord, are running a 10km fun run in aid of Cancer Research and Help for Heroes on Saturday 27 April. The endeavour, named 10k for 10k, aims to raise £5,000 for each charity and judging by last year's photos, they take their fancy dress very seriously. After the run there will be a barbecue, live music and karaoke. Donations for both charities can be made via their webpage.
Spring, why art thou so coy? A washout Saturday, a breezy-bright Sunday, but now we're back to cloud again. As people say in comics, but never in real life: "Harumph". Still, with highs of 16°C today, and a fickle-fackle sun, we might yet biosynthesise some more vitamin D.
