Below, tennis legendBillie Jean King, who has anew partnership with e.l.f.

SKIN,reflects on her friendship withAlthea Gibson, the first Black player to win a Grand Slam title.

Billie Jean King reflects on Black tennis player Althea Gibson.

I first saw Althea at the Los Angeles Tennis Club.

That was back in the 50s, when I was 12 or 13 years old.

Althea was the No.

1 tennis player in the world.

I took in everything that I could that day.

I took in how she played.

I took in her power, her finesse.

I watched her strategy.

My parents had taught me that every generation gets better.

So I thought, That means I have to be better than the way shes playing?

She was fantastic, and it made me work even harder.

We didnt have professional tennisuntil 1968; thats when we first got a check.

If youre an amateur, it means its a hobby.

You dont make money.

Well, this was not a hobby for any of us.

I was lucky to get to know her through the years.

Our first significant conversation was at Wimbledon.

This was probably 1966 or 1965.

She was in the locker room, and we started talking.

She has a deep voice, melodic and beautiful.

I loved listening to her.

And I just learned abouther journey.

We always stayed in touch after I got to talk to her at Wimbledon.

For a while, she was depressed and wouldnt talk to anybody.

Id leave her messages all the time on her phone: Thinking about you.

Id love to come and see you.

Is there anything I can do for you?

1 in my heart and mind.

Her friend told me she was getting the messages, and she did mention them later.

In those days, people were very quiet about when they didnt feel right or were sad.

She meant so much to so many of us.

She led by example, I think, more than what she said.

I watched how she carried herself and listened to her stories.

Without this woman, I wouldnt have known what No.

1 looks like in our sport.

Seeing it is really helpful in imagining it for yourself.

Especially in a profession like sports, you have to really watch a lot of the other people.

Watch what they do, watch how they win,whythey win.

The champions know how to win.

I have this saying: Pressures a privilege, and champions adjust.

When I say champions, I mean champions in life and on the court.

Althea showed me both of those.

As told to Leila Barghouty.
