Too bad it's a shitty scan and only available in 725x1047, from a website that claims

Texas Instruments engineer Gordon Teal invented the first silicon transistor based on germanium.

Which element is it, then?! You had one job!

I had to waifu2x to make it decent. You can take the isolated streaks at the top, stretch them with Krita and apply the Divide blend mode to "subtract" them from the image. I don't think you can eliminate them completely without some special tools.

Alternatively, here is a streak-free but not much better scan from the Electronics Magazine from June 1954.
