Here's I. M. Pei.
Chinese-born American architect; designed Louvre Pyramids; Rock&Roll HoF

Not sure I like the contraction of Rock 'n' Roll Hall of Fame to beat the guillotine on number of characters but the semi-colon after Pyramids should make him an inductee of the Hall of Fame rather than its designer.

Jesse Chisholm's description has a reference to the Chisholm trail in it.

Percival Lowell - Initials in question.

Fictional character - Lorna Doone

Minor White - American photographer; taught at MIT; curator of George Eastman House; co-founder of 'Aperture'

Nicely done L_T.

Thank you, mehaul.

I had a good set today, with four which would benefit from rewording:

Charles Halle - founded Halle orchestra

Charles Hambro - Baron Hambro

Chas Hodges - singer with Chas and Dave

Neils Abel - Abelian groups

Two more for review, L_T:

Joseph Louis Lagrange - discovered Langrangian Points

Harry G. Selfridge Sr. - founder of Selfridge's store

I got those in today's set and noted them, thanks.

Vincent Lopez - Initials in question.

In today's question set 17 (difficult) I had Johann Strauss I, described as "Austrian composer; father of Johann Strauss II."

Georg Ossian Sars - definition includes 'son of Michael Sars'. Mind you, I was glad to see that as I'd never heard of him!

Today's Question Set 16 (difficult) identifies Elihu Yale as "British East India Co. agent; founder of Yale University."

Odd Aukrust - brother of Kjell Aukrust.

I'm none the wiser - he's going to the top of the list instead of the bottom, as I am intrigued to find out more.

You will let me know if Odd's sibling's name is Even, won't you?

Who besides me looked up the information for Odd, Kjell, and cousin Tor?

Haven't got time to work up a new description until at least this evening when I get home from work, maybe tomorrow morning if I am as exhausted this evening as in previous nights this week - but I will post it here. I will also check if any of the others have entries, and what modifications might be needed for them. It has surprised me to find a number of people identified by relatives who aren't listed in their own right.

Uncle Olav looks the most interesting one of the Aukrust family, although they'd none of them appeared on my radar until today.

Fictional character - Bathsheba Everdene

A new one to me:

August Krogh - Danish zoophysiologist; developed the Krogh principle

I got this one today.

Edna Pontellier - "Fictional character; female protagonist of 'The Awakening' by Kate Chopin"

today's set 20

Modesty Blaise

Two issues in today's set.

"Rudolph Isley" - his name is mentioned in the description.

"Dennis Ritchie": the description mentions his initials.

From today, an extra set of ( ) around the last name:

Jamaican-born female singer-songwriter; 'My Boy Lollipop' = (Millie (Small))
